Being present is being connected to All Things.

If the many worlds interpretation of quantum mechanics is in fact true then the universe is deterministic, but we are faced with an interesting philosophical question of identity. Since all possible outcomes exist simultaneously, it's not surprising we find ourselves asking and existing as the question must be asked by those who exist, can and do ask it, wherever and whenever. However, why exactly does our life as an individual take this particular path instead of some other? For physics they're all equal. Futhermore, if time doesn't truly exist, why/how do we experience present and flow of time?

True free will cannot exist in a deterministic universe and therefore our path cannot be determined by one. If there existed no subjective experience of specific consciousness then the question would perhaps vanish. From purely physical point of view, I suppose there doesn't have to be anything special about every possible past, present and future existing simultaneously, but from the point of view of our consciousness, it's deeply mysterious. It may of course be that in some way consciousness is just an illusion and there is nothing special about this particular experience. Though, the illusion does appear to be extremely convincing.


Occasionally one runs into discussions about the simulation argument according to which we almost certainly live in a simulation because if simulations are possible and run then there are going to be very large amounts of them. While this is certainly somewhat entertaining argument, there isn't particularly much one can deduce from it. Whether we are in a simulation or not tells us nothing about where these simulations ultimately originate from and also doesn't tell us anything about our place in the hierarchy of the simulations (for example how deep we are from the fundamental underlying universe), unless of course we can somehow acquire empirical knowledge concerning them.

Quinine in tonic water converting 405nm (violet) laser light into 450nm (blue) by fluorescence. Diluting tonic water down to a single quinine molecule should allow antibunching to be observed by a detector capable of resolving single photons on timescales less than fluorescence lifetime of 20ns. Only a single photon from a single emitter on average within fluorescence lifetime can be emitted regardless of the number of photons in the exiting laser pulse.
Also, what might be worth considering is that at least in this particular universe (or simulation) all systems whether they be simulations or not, appear to interact with their environment to some extent and it is in fact impossible to create a perfectly isolated systems. This is why for example row hammer exploit [] is possible. Therefore no simulation is fundamentally any different from just a weakly coupled system in the most fundamental underlying universe. In certain sense creatures living in a simulation are then nothing more than caged animals born in captivity. Not that different from what we are now (as we are also caged by at least the limits of our current physical bodies and consciousness). Of course no particular reason why this couldn't change in the end.

What ought to be done?

What we are forced to ask every now and then is, what do we truly want?

This question kind of contains all meaningful questions concerning morality, ethics, right and wrong and in general all conceivable oughts. Even when we ask if we have the right to decide this for some other species, we're simply asking what we truly want - what kind of rights we wish to grant the other species. It's all on us whether we want it or not.
Of course we also have to ask ourselves more specific questions like what we want as a group or as a species and at the same time what we want as individuals, but these are simply extension of the "other species". These are the only meaningful prescriptive questions. Even if you're a religious person, the situation doesn't change very much. Your deity might act as an additional source of prescription to you and you might think you have access to their prescription as a description, but I posit that you are still faced with the exact same questions as the rest of us who don't believe. You need to ask yourself how you wish to value your supposed deity's prescription and determine what, if any, describes your deity's prescription most accurately. It's all on you. Even the methods are exactly the same, your very own reason and judgement.

What is the origin of their will and motivation ultimately? Why they feel thighs ought to be one way instead of the other? My limited understanding is that our motivation is a result of natural selection, history of our species, our personal histories and partly because of the history of our societies. However, going back even further, it would appear that these are simply arbitrary coincidences, some of which have served our species well in the battle for survival, some less so.

These are arbitrary preferences. Generally people prefer to continue to exist and avoid suffering for example, but what is generally considered moral varies from group to group and the extent that it doesn't vary, appears to be mostly simply due to our biological similarity.

Knowing this does not limit us from acknowledging the consequences, for example, we understand it is likely in our interest to grant certain degree of equality to other people, given we don't know how our own lives are going to evolve. We might be the other people one day. It's like gambling, but for a rational person, it's not really gambling, it's investing. It could fail, but it's still better to play the stock market than it is to play the lottery.

Unavoidable conflicts between dissimilar groups are perfectly expected, but luckily most groups are at least somewhat rational and optimize by compromising. However, it is conceivable that conflicts that cannot be solved by negotiation might emerge. These are normally called wars and the worst ones are about survival and extermination rather than anything that could be reasoned.

Once we've determined what we want as a species, we only need to figure out how to best approach that goal. There basically exists only a single method to answer these question for us - science. Science is nothing more than a name for the rational process of fishing out the best model out of all the possible descriptions out there by any means imaginable. Science gives us a description of the universe including its inhabitants - us, and tells us how to best achieve our goals and what outcomes to expect given specific choices. It doesn't tell us what we ought to do. That task is left for us.

Every decision has consequences, typically both good and bad, often unavoidable. There are many ways to make a decision, none of which are necessarily any better than the other. We can aim for least suffering, most pleasure, least boredom, maximized fairness, longest life, maximum number of lives, maximum knowledge, maximum safety, etc. Many of these are mutually exclusive. Most pleasure could mean most suffering. Longest life could mean most boring life. Least suffering almost certainly means minimum number of lives. We can expect negative consequences due to our decisions as well as positive, there will almost certainly always be some of both. Maximizing the number of people is not going to maximize the quality of life for an individual, it might not even maximize the total sum of happiness. Not to mention it probably won't maximize the long term total sum considering all the generations to come who will have to live a life of scarcity when resources have been depleted by the previous generations. Some alternatives are obviously excluded, like maximum suffering. Although, it's not entirely clear we know how to do this either, because what is bad for the humanity now, might be good for the humanity later if we manage to save the planet and its resources for times when they can be more efficiently used. Economic growth tends towards faster depletion and increased rate of destruction. Diseases limit the number of people and save the environment. None of these alternatives are trivially good or bad. Never the less, to deny the nature of this answer, not to mention the existence of these questions and knowledge concerning them is to deny the truth and to deny who we are. We know that doing one thing now will favor some and hurt some others. Not deciding has its own consequences as well. That is the nature of the game. We shouldn't just ignore it.

The barrier has begun to yield

The following papers might have tremendous implications for astronomy as they imply telescopes far beyond our current ones can be built without making them any larger. In other words, they've beaten the diffraction limit, even for incoherent astronomical light sources.

In case you're unfamiliar with the diffraction limit, for telescopes it says that the ultimate limit for angular resolution is a function of the used wavelength and diameter of the used focusing element. For a microscope their resolution is a function of the wavelength and the index of refraction. That's why astronomical telescopes tend to be huge and microfabrication uses shorter wavelengths.
We already knew superlenses existed, but they were mostly limited to near field. Spatial-mode demultiplexing on the other hand can be utilized to beat the diffraction limit in the far field as well. While not entirely surprising, it's not everyday news. I can't wait to buy a telescope that allows me to see the footprints on the moon (likely not going to happen anytime soon).

This method has some similarities to Fourier transforms in a way that is decomposes the spatial modes of the electromagnetic field into orthogonal components that not only carry information about the amplitude, but phase as well.
Here's an unrelated figure.
Subdiffraction incoherent optical imaging via spatial-mode demultiplexing

"The seemingly infinite enhancement offered by SPADE does not imply unlimited resolution for finite photon numbers. Provided that enough photons can be collected, however, the giant improvements over direct imaging should still be useful."

Far-field linear optical super-resolution via heterodyne detection in a higher-order local oscillator mode

"If our technique is used with state-of-the art microscopes, precision on nanometer scales can be expected."

Achieving the ultimate optical resolution

"Our results stress that diffraction resolution limits are not a fundamental constraint but, instead, the consequence of traditional imaging techniques discarding the phase information."

What can be shown, cannot be said.

When something is "known for certain" and we cannot doubt it, then we cannot truly speak of knowledge. An experience is something like this, it is rather like a simple reaction, an unavoidable brain state dictated by a thin causal chain, a quale (plural: qualia) if you will. Being our brain state, an essential part of what we are, we by definition cannot doubt its existence any more than we can doubt our own existence. This causal chain is what allows us and in fact forces us to be conscious and experience things, but knowledge is something more complicated.

Being unique to our particular brain states and history, it should not be a big surprise that qualia can never be communicated to others. We are all individuals and live unique lives, and this forbids anyone from truly knowing what it is to be some other individual. We can only communicate our experiences to others by assuming a degree of similarity, but you can never truly tell a blind person what it is like to see and you shouldn't expect to. After all, the causal chain leading to the experience of vision cannot be the same for the blind person as it is for the one seeing. Simply telling the physical facts does not reproduce this causal chain and therefore cannot lead to the same brain states.

So experience is an integral brain state to the existence of our consciousness, but existence of that state does not represent the nature of reality or fundamental truth underlying all of existence in any obvious way besides perhaps simply by existing. Qualia alone tells you nothing about the underlying reality. Like an apple falling from the tree, it has no particular meaning before meaning is assigned to it by a consciousness for example by using complicated correlations and words like apple, fall, tree and such that point to some interpretation, model, history, reoccurring experience and most of the time the ability to share these experiences to certain degree with other similar creatures of our kind.

Experience cannot be said to be primary or secondary representation of truth without interpreting the experience, and immediately when an interpretation is made, a claim is made. Something is said using some kind of language and the claim becomes subject to doubt. By building beliefs which are consistent with each other, i.e. increasing coherence, we are building knowledge.

All knowledge is uncertain, if it isn't uncertain, it isn't knowledge - only a reaction. We can never be sure of what the fundamental nature of the universe is simply based on our experience, but this does not prevent us from playing the game by building coherence. This has undeniable utility and allows us to experience a life much more diverse than that of a mere reacting puppet, even if we fundamentally still are only some kind of puppets of the "second degree", without true free will, but at least we're no longer simple puppets of the "first degree".


It is suggested that quantum entanglement emerges from the holographic principle stating that all of the information of a region (bulk bits) can be described by the bits on its boundary surface. There are redundancy and information loss in the bulk bits that lead to the nonlocal correlation among the bulk bits. Quantum field theory overestimates the independent degrees of freedom in the bulk.

Quantum bomb

This is an experiment in which we wish to detect the presence of a bomb B without detonating it. However, the bomb will automatically detonate even if only a single photon hits it. One might intuitively think such detection is impossible, because in order to see something, one needs to shine light at it. However, turns out this is in fact possible and here's how.

A polarised photon is injected into the device and it experiences a rotation of A degrees by the rotator each time it passes through. It is passed through N times such that N*A = 90 degrees before being ejected. After the rotator the light is split into horizontally and vertically polarised components by a polarising beam splitter (PBS). The bomb is placed in the path of the weaker signal and the signals are combined with another PBS afterwards. The photon will remain polarised in the original orientation only if there was a bomb that prevented polarisation from being rotated. The probability of setting off the bomb is sin(A)^(2N) which approaches 0 as N approaches infinity and A approaches 0.

This outcome is a consequence of the fact that insignificantly small amount of light lost in one of the arms will prevent a large amount of light from rotating over a large number of circulations which would detonate the bomb. This works simply due to the fact that the lost light compared to the total in each rotation is insignificant compared to the rotation. While the polarisation is rotated by A, it's not difficult to see that loss becomes insignificant respect to A as A becomes small. Never the less, it is the elimination of this small signal which prevents the rotation from accumulating and consequently makes detection without large interaction possible. It is also closely related to quantum Zeno effect.
Rotation by 1 degree
This works even with a classical signal if the detector simply consists of light level detector which is set off when some threshold is exceeded. The only quantum mechanical aspect of this is that it will work with a single photon as well, implying that the photon didn't simply take one path or the other, but actually took both. One might also say that its wavefunction collapsed into one single polarisation each round because of the presense of the bomb. The experiment would seem to imply that these extremely small subphoton amplitudes are in some sense real even though one can only detect single photons.


This paper [] seems to be of the opinion that the universe is discrete and finite. I'm sure some people find it pleasing.

Though, next of the previously unvisited locations I was thinking I might visit India, Nepal, China, Japan, Thailand, Vietnam, Australia, New Zealand, Israel, Argentina, Chile, Yukon, Alaska, Hawaii and then perhaps Africa in some way. Brazil, Peru, Korea and Russia might be worth visiting at some point as well. Not necessarily in any particular order. Of these locations I'm thinking Japan, Australia, New Zealand, Yukon, Alaska and Hawaii might be decent enough to visit alone, but I'm thinking other location might be nicer to visit with some company.

At least some rules can be bent...

...but not all of them are worth the time it takes.

Even if 99% of people are idiots, 1% is still plenty, and even if 99% of the things that the 1% does is idiotic, the remaining 1% is still amazing. That's the highest compliment and respect I can genuinely offer humanity. It's not exactly that people are stupid, it's something else, but there's definitely something weird, perhaps something wrong.

You can have something like soul, afterlife, rebirth and immortality from science. There are many ways. Maybe not particularly likely ways, but possible ways none the less. Perhaps you can even have a nearly rational reason not to kill yourself for a nihilist who values nothing, but the minimization of their own suffering. If quantum mechanics is true, there is a certain likelyhood that your essence will once again re-emerge as a continuum of your current consciousness (after more than astronomical timescales). It's only a question of how much suffering occurs between these occurrences and I would speculate that such suffering might be quite large and it would in fact be in your favor to live "forever" and strive for maximal control of your own experiences, even if your life was to be mostly mundane, uninteresting and to some extent pain. As long as you hold some power over your own destiny by staying alive as opposed to being dead (or "in between"), you might be better off. Not that you'd actually have any hope of control with these timescales, but one can always dream and at least you would maximize percentage of the time you are in control. Though, in general I'm in favor of persons right to end their life at will without regret should a need arise due to excessive pain or whatever. Anyway, in my ideal world, people would not die of old age or disease, but by their own hand and will after having lived a life they consider sufficient, some might perhaps say after having become bored of life. Whether that be 100 years or 100 million years.

"Necessitarianism is stronger than hard determinism, because even the hard determinist would grant that the causal chain constituting the world might have been different as a whole, even though each member of that series could not have been different, given its antecedent causes."

What exactly does a hard determinist believe then? Is hard determinism defined well enough to answer this question? That there exists a random element to the way the world came to be? Where does random come from? Even though I'm a necessetarian, I can still make estimates of the state of the world and what would constitute a better world for me and others and how to go about it as long as I acknowledge my finite understanding of what is necessary. I'm simply an agent of necessity even when making these estimates. My experience of choice is simply an illusion, but it's a wonderful feeling none the less and no one can take it away from me.

When I inform you that you have misunderstood my position you need to acknowledge this and attempt to correct yourself before proceeding to attack my position, otherwise you will simply waste everyones time by continuously engaging in irrelevant strawman arguments which have nothing to do with my true position.

I'm not saying (necessarily) that your argument has formal flaws, but there's no point in engaging with the argument itself before we get over the justification for its premises and as far as I'm concerned, we're nowhere near. We should properly acknowledge that if the premises are not sound then the potential formal validity of the argument implies nothing of the truth and is quite irrelevant.

If your god existed and it was his will then he would find a way to convince me. As this hasn't happened, I can only conclude that he either doesn't exist or wants to remain hidden, both irrelevant to me.

"Never waste your time trying to explain yourself to people who are committed to misunderstanding you."

Not only is all matter and energy just a vacuum fluctuation. Time and space are vacuum fluctuations as well. You lower a particle with energy E=mc^2 into a black hole and it loses all of its energy and with it both time and space cease to exist, assuming they had any independent existence to begin with.

What kind of person would I theoretically consider an ideal girlfriend (to the extent such a thing can make sense for me)?

A person who does not want to have children under any circumstances and has no (intrinsic) will or need to use intoxicants or be religious. The first appears totally essential, at least as far as I can see, there would be irreconcilable conflict otherwise. The only theoretical circumstance (if one wishes to be not entirely absolute) might be if I was ultra rich, like on the order of tens of millions of euros (and/or immortal). Only then the price would not be too high. The last two are something simpler. I experience them as a strong preference mainly for emotional reasons and I have supporting evidence of their value in the form of naturally increased feeling of trust, comfort, respect and other small things which seem to come with the package, but they may not be trivially essential if the conflicts are not large and may be shadowed by other things. Minor controlled conflicts may even foster valuable diversity under some circumstances and may lead to higher value for the sum of all things, that's why I'm never quite absolute even if it might sometimes appear so. The optimal balance may be very difficult to achieve though.

As I have very little tolerance for negative emotional expressions and irrational behavior, it would be quite essential for my company to naturally behave in a manner consistent with this. I also strongly prefer people who are pragmatic, empathic, intuitive on a wide spectrum, motivated, positive, patient, faithful, dedicated, trustworthy, unprejudiced and in general kind and goodwilled. I'm a strongly independent and introverted individual who needs certain distance, personal space and time. Therefore, in order for both of us to enjoy each others company, these qualities would probably need to be shared to fair extent.

I see my life as a personal expedition rather than a routine, achievement, competition, ladder or any kind of typical structure with stereotypical goals. I can value friends, their support, their entertainment value, their diversity, their intimacy, shared experiences, perhaps even a single special extended friendship with closer emotional ties to the opposite sex, but I find it unlikely I would ever see or want anyone to be much more than that and even then people for me are only for the good days, on bad days I prefer to stay alone and away from anyone or anything.

I strongly prefer people who are in tranquil and healthy equilibrium with their mind, body and emotions. People who consider their body a temple without totally excluding the value of small healthy or nearly healthy indulgence on occasion. People who have no will for permanent decorative modifications and who despise vanity for the most part. People who are not bound by any rigid ideas, opinions, goals or habits. People to whom most things are not a big deal. Perhaps one could even say, the eccentrics who are just a little bit above or at a distance from their culture, society, upbringing, social group and in general everything. Timeless people, perhaps healthy nihilists. Someone who is consciously their own individual and do not primarily compare themselves to others even though they are always willing to learn from others mistakes. Someone who is not afraid to fail. Someone who does not primarily work to please others or conform to any groups. Someone who considers an experience, whether emotional or otherwise, mostly as a case of diversity, a thing to learn, discover and enjoy for its own sake rather than some consumable or essential, least of all routine. Someone who at least in principle always strives to outdo oneself without considering themselves incomplete or defective.

In general most of these qualities are something I consider relevant to my emotional comfort, trust and respect, not to mention pragmatism. Some are more essential, some are less. I think many of these are a lot to hope for based on my experience of the human race as it presents itself in this time and place. This is one of the reasons why in general I have never found it very worthwhile to waste much of my time or effort for such aspects of life. I have never been particularly interested in having any relationships of the typical kind or particularly concerned at all, at most I would say I've had some interest in having some kind of comfortable diversity in my life. Some value can be found if a person can constructively challenge me on matters I've been not exposed to sufficiently even if they possess some uncomfortable qualities. This list is of course to large extent a list of my own personal character traits, but there are also some which are to lesser extent descriptive of me than I would perhaps hope them to be.

Then again, I'm not sure I could actually be bothered to have anything. Conscious creatures tend to be bothersome even when they're fine, and I'm bothersome too. Perhaps if the circumstances were close to perfection, but they never are, are they? What would be the point otherwise?

In some sense people are only entertainment to me and my altruism is only a manifestation of the valuation of diversity for my personal purposes. Never the less I consider it likely that as long as I live as if I have a chance to live forever this way of thinking could in principle make my behavior maximally good (by some hypothetical average standard based on shared values of conscious creatures as far as we can understand such) and perhaps in practice more moral than the behavior of many other people. As a scientist rejecting all absolute points of view, I am forced to believe anything is possible and therefore I am naturally bound to the maximally good path. I will strive to save the planet, its inhabitants and optimize their freedoms for myself for selfish reasons, but I will do all that none the less. If I find a mistake, I will strive to correct it. Whatever I might benefit from other people, they should symmetrically benefit from me as well. Like the veil of ignorance, I should rationally do onto other as I would have them do to me, one way or another. Sometimes I might even be kind for the sake of being random or perhaps one should say diverse.

"God" help if I ever lose my will to live, luckily doesn't seem very likely to happen though as I seem to have it in my blood to go on forever so to speak.

If you're hammer then all your problems look like nails.

What if things happen just because they're there? The world, as I see it, is exceedingly arbitrary.

I don't remember who said it, maybe nobody, I don't care, today I said it.

Raspberry Pi controlling a cheap digital frequency synthesizer. Some scaling needed for more interesting results.
Life is too short for anything reasonable, but I guess one might still figure out a way to have a little bit of fun by accident.

Never waste your time trying to explain yourself to people who are committed to misunderstanding you.

Anything I can't place a probability on I'm just going to ignore, because that simply means I don't know anything about it.

Relative phase stability of rtl_sdr sticks with common crystal doesn't seem too bad (100 MHz).

Your favourite friend is the one you can watch 9 consecutive episodes of Dexter with, without exchanging a single word. The foundation of your friendship is built on a mutual dislike of other people. Everyone else can only be tolerated on a bi-monthly basis for no longer than two consecutive hours at a time.

This one running now at 2.4 GHz sample clock. Should probably go with 3.2 GHz.
However, I need a nice OCXO for that, and I don't have one at the moment.
Also, I had some trouble with quality of my low voltage (1.8V/3.3V) supply (current demand is pretty high).
You often wonder why people can’t be more like you. You have mastered the art of minimal communication and as far as you’re concerned it’s working. You are awesome, hilarious and delightful, after coffee, over text, to people who actually care about what you have to say. Why can’t everyone else take a leaf?

Children irritate you for no reason what-so-ever. Their energy and spirit drains you. You often wonder if child-free restaurants are actually a thing and keep mentally reminding yourself to Google it.

You are convinced certain people exist for the sole purpose of pissing you off. Everyone has a purpose in life. This must be theirs.

We wouldn’t dislike most people, if people weren’t so ridiculously annoying. We have accepted that our every day life is going to be filled with interactions which we can’t be bothered with.

Sample clock 2.5 GHz now.
Spectrum analysis using rtl_sdr (this one goes up to 2.1 GHz) shows ~1.25 GHz peak on the computer to the left.
There's some crap above the Nyquist limit, nothing to worry about.
