They do have a working prototype; it's in the video. Also, your comment is ironically pretty dismissive. As an expert, do you think that the sporadic time/money cost of changing a tire could offset a significant reduction in fuel

"Well, it's a fraction of the cost to operate, but if a tire blows, the mechanic will have to detach a piece of plastic. So I think we'll pass."

You can pick a blue and a yellow and a proportion at which to mix them which will produce white, but for any two primaries you pick, there are a multitude of colors you can't represent. For example, if your basis is blue-yellow as you

No. It goes through both. That's the weird thing that double-slit tells us, especially because it remains true even for "one photon" (i.e. one quantized energy packet arriving somewhere on the detector screen).

A few thoughts: The Monty Hall comparison is about shifting human knowledge about an underlying system with a definite state. What, then, is the source of the uncertainty in QM in this author's view? It is not our knowledge about the

The sky is blue and the sun is yellow. Subtract the sun and you are left with only blue light from the sky. ...which explains why indoors, shadows /do/ tend to be colorless: http://www.camilleprzewodek.com/uploads&

No, I mean that there are no particles. Only waves. Only that if you try to measure something about the wave, you will always get a discrete "yes/no" answer.

Personally I think the concept of "particle" needs to go away completely. I think really what "particle" means is that "all measurements are quantized". But the probabilities of any given measurement happening

All of those things about visual processing are true. > You can't reduce it to three axes. This is my claim: It is possible to represent all possible visual stimulus with: f(direction, time) -> (a, b, c). That is what I mean by &

The statement I take objection to is this: > The fact that colors influence colors around them means that there are far more than 256^3 viewable colors: the spatial axis is like a fourth channel. That the perception of color is influence

by tbabb 9y ago
Perhaps a nitpick, but 256^3 doesn't really represent anything about human perception-- it's just how we store colors in computer memory. The human eye can perceive a far wider range of colors than any screen can (currently) repre

If by knowing the structure of a NN a "trick" image can be specially crafted to fool it, what is the equivalent for a human brain? If we get to the point of having a human connectome to analyze-- or the kind of access to neural to

I think his point at the end was that computation is substrate-independent; i.e. there is nothing special or magical about silicon and electricity. In a sense, the universe itself can be said to be acting like a computer.

That should be Nick Bostrom's face at the end there; not Elon Musk's.

EDIT: Not healthy, though, if that 2% is a quota, rather than the happenstance fraction of people who fall below the performance bar at evaluation time.
377.
by tbabb 9y ago
Do they set a "quota" for 2%? Or is it that they do it every year, and 2% is about the number that falls out? I do agree that a "firing quota" is backwards; it should be a standard of performance. But even in a healthy,

by tbabb 9y ago
The high estimate was 700 fired. Out of 33,000, that's 2%. Culling the bottom 2% performers seems like a reasonable (even healthy) thing to do; not really an upheaval.

I suppose some of it would be lost to the vacuum of space, though it would have to be an impressively large space transport market for that to start making a global difference. Also weird to think about the long-term implications of Earth&#

Back of the envelope calculation for the price of an Earth-to-Earth ticket: Musk's stated goal is $500k/ticket to Mars. It's a shorter trip, so perhaps ~5x as many passengers in the same volume (i.e. 500 total; cf. a380 which

Agree; in fact I'd go further and say that anxiety is by definition irrational. If it were rational, it would simply be "worry", which is useful. The difference is that in the case of worry, it makes sense to mitigate the e

Not to mention that the value of a currency, like everything else, is driven by supply and demand; so in the face of fluctuating demand, adjusting the supply is necessary to ensure the currency measures a consistent amount of wealth, and do

You are right that bitcoin is a commodity, but I disagree about your condition for currency. It doesn't suddenly become money when some government "recognizes it" in an arbitrary way. People make comparisons to gold, but gold

It is fantastic to hear this from a seasoned academic about his own field-- People get trapped in orthodoxy and become unconsciously unwilling to explore bold ideas in favor to minor tweaks. The framework of thinking itself becomes precious
