To say that theoretical physics has been ahead of experimental physics from 1905 onwards is not entirely accurate. In the 1960s particle accelerators had found lots of particles. At first those were thought to be elementary, but more and mo

Precisely! So that is your argument for why prohibiting him from saying that was legitimate (firing somebody for behaviour X is pretty much the definition of a company prohibiting behaviour X, I mean, what else can a company do?).

If the hiring practices do in fact lower the bar, should he still be prohibited from saying that?

Or that repression of alt-right views is actually counterproductive.

The literal translation of "What do you want?" is "Wat wil je?", and this is considered impolite. You're unlikely to hear this from a Dutch waiter. You might hear "Wat wilt u?", but even this is rather cur

The notation is very simple: you write tensor expressions with indices, and repeated indices are implicitly summed over. For example, matrix multiply: A_ij = B_ik C_kj Differentiating this with respect to variable l: ∂_l A_ij =

What do you think about the index notation physicists use for tensor calculus?

How about this: we treat people as individuals regardless of what the scientific facts turn out to be.

I don't see why that would work. If the last digit is 0 then the number is not prime. Even if you make the bottom right corner a 1, it is not clear to me that any image will give a prime for sufficiently large canvas. The reason the or

Maybe it can be reduced to something simpler, because this is the first proof and proofs are often simplified later, but as far as proofs go this one isn't that complex.

I don't think that tactic works poorly in that format at all, it's just that this person is incredibly good at defending against it. Very few people could withstand such an interview.

What would the price be if all the speculators pulled out, and only the people who genuinely use bitcoin for transactions remained? Why couldn't this happen to all the major cryptocurrencies at the same time? In fact, if it happens, is

Things aren't nonlocal in geometrical optics though. Something happens at C at the instant in time when the particle is at C. You can start a ray at any point in any direction, and just follow a straight line until you hit something. T

On the one hand, I like that they're doing old physics. There is a tendency to do only cutting edge physics such as modern quantum mechanics research, particle physics, even string theory. There is little chance to convey an accurate u

You're describing quantum mechanics, but the phenomena here are classical. There is no mystery with Fermat's law, even if you do not accept wave optics and want a theory of light particles. At each instant in time a light particle

There are other particles that move at the speed of light (gluons, gravitons), so in that sense, light is not special. Classical mechanics can be formulated in Lagrangian form such that the path that a particle takes is the path of least ac

Why don't you start a communist commune? You can do that in a capitalist system. You can't set up a capitalist commune in a communist system because they'll put you in the gulag.

It's not a question of blame, it's a question of the results of a particular policy. Rent control creates an incentive for landlords to bully their tenants. You can create another government agency to police this, but in reality t

In an ideal world you'd run the experiment and see how it goes. In the real world you'll probably be stuck with it regardless of the outcome, because there will be a concentrated group who will be strongly against ending it, where

It is speed, the speed of light. Particles that have zero mass go at the speed of light. This is a property of the particle. That there is a maximum speed is a property of spacetime however. Even if there were no massless particles we could

You can't move with the speed of light. If you move at 99% of the speed of light away from the star you do see the star but it will look red because the light waves get stretched out. Photons indeed have the special property that they

From a modern perspective the relation of the time axis to the x axis is roughly the same as the relation between the x axis and the y axis. Saying that two events happened at the same x coordinate (delta x is 0) is a statement that depends

At a very high level the univalence axiom says that set operations may not look at the elements of a set. Consider the cartesian product versus set union. The cartesian product does not look at the elements of the sets, but the union does.

For very large values of large enough that is always true. Even on the condition that they use the Latin alphabet and have exactly the same set of words and exactly the same set of meanings of words, there are still n factorial ways of assi
