No, it's not wasted; that's my point. Why don't you think Disney's investors demand a $7bn annual saving by cutting the "waste" on advertising? The spend on fundraising does go tow…

The criticism that too much goes to fundraisers is meaningless without an explanation of how much would be optimal. If spending an additional $1m on fundraising meant an additional…

I had a major epiphany deriving this myself as a teenager, because it was the first time I used algebra to calculate something "real". The equation was trivial, but the principle o…

Meat is a $2 trillion industry globally but you're primarily worried about the corrupting influence of activists' donations?

Good for you, but NAC has a host of effects so you couldn't say it was due to glutamate for sure. For example, NAC mainly increases glutathione, the primary antioxidant your body u…

I'm not sure that those really are the extremes. I think quite a lot of people believe that justice may or may not ever happen depending on how we choose to act as a civilization. …

No, 63.3% of all participants got a favourable outcome, so 13% cheated (suggesting 26% would cheat if necessary, as half got a favourable outcome without cheating). The participant…

The Bristol Four acquittal was not an act of jury nullification. Under the Criminal Damage Act 1971, no offense is committed if there is a "lawful excuse" for the damage. The defen…

I see why you would say that: these neural networks probably have thousands or millions of weights while the equations of motion can probably be written on an index card. But I wou…

I would say it's essentially equivalent, especially if you choose a neural network architecture with a very low-dimensional layer in the middle with only a handful of variables. Th…

It is just a model though! Everything in science is just a model. We better hope it's just a model, because it's incompatible with quantum field theory, which is another very accur…

I don't see any fundamental difference. A deep neural network is a universal function approximator. It uses different language from what we're used to (weights and activations inst…

But he's saying it is bad to do it that way instead of doing traditional physics because you get no understanding, which is true, but in this study they're not using it as a "physi…

Who cares if there's no gravity? Gravity wasn't sent down to us from heaven on a stone tablet, it's just a concept that lets us make predictions. At school I was taught it was a fo…

It's really easy to test whether or not it works - see how well the model predicts on out-of-training sample data. That wouldn't work with astrology. There's no such thing as "phys…

It's true that there are many mathematically equivalent ways to describe physical systems. But the important point is that some are more useful than others. For example, Lagrangian…

I'm not sure why you don't think it's Physics. It's about formulating laws that describe the behaviour of physical systems - that's the essence of what Physics is. I have a PhD in …

I don't see why that's relevant, a video camera is just another instrument that records data, not essentially different from the detectors at the LHC, albeit completely un-optimize…

You seem quite mistaken about what "caveat emptor" means ("buyer beware"). The person you're replying to means we should be cautious about using risky unregulated light boxes, whic…

I think this misses an important factor in that the sensation from walking on lego is unpredictable because the corners stick in random parts of your feet, which means you can't br…

That's not exactly right; in British English and other dialects that don't say "legos", we don't have a plural of "lego" because we treat it grammatically as a "mass noun" just lik…
