Could you please explain how the satellite observing the arctic sea ice affects climate change? As far as I can tell, until this past year (the paris climate agreement) that hasn't been a significant effort to reduce carbon emissions o

I second this. The first book was a little slow but the second and third were two of the best and most thought provoking books I've ever read.

You made the original claim that it violates relativity so why don't you take your own advice and be more explicit. The current accepted size of the observable universe is ~90 billion light years in diameter. If you were referring to

I didn't quote you or claim you said anything. I made some assumptions about why you made certain statements like the fact that you think the Universe being ~90 billion light years in diameter violates relativity (it doesn't and t

It does not actually violate general relativity. You can read the response to the post you reference for some more details.

There is a difference between the size of the observable Universe now and the size when the light was emitted. It does not violate relativity to state that objects that were 14 billion light years away when the light we see from them left a

The acceleration of the Universe has not been constant. In the very early Universe there was a period called Inflation where the speed of expansion was much much much faster than the speed of light.

I believe the concept is a little different than what you stated. It starts with the assumption that the Universe is actually in or very close to a maximal entropy state, which is orders and orders of magnitudes more likely than the low ent

I will admit that had there been a better sea wall the Fukushima incident would have much less severe. But I still think it's beside the point. As to your point about passive safety systems only working for a finite period of time befo

When people think of the Fukushima disaster the two direct and unfortunate deaths caused by the insufficient sea wall are not what come to mind. The meltdown of the reactor is the primary concern. If a meltdown had never occurred the Fukush

I agree with you. There are undoubtedly issues with nuclear power but the possibility of a Fukushima/Chernobyl meltdown happening in your backyard is not one of them. The main downside is that this understandable but unfounded fear get

by Analog24 10y ago
The Fukushima reactor was old and outdated. Modern reactors are built with passive safety systems that essentially make it impossible for a Fukushima style meltdown to occur. Ignorance and coal are not the answer.

This is flat out false. in addition, the physical withdrawal from alcohol addiction is significantly worse than the symptoms from opioid withdrawal. Alcohol withdrawal can actually kill you. My father was a severe alcoholic (i.e. physically

Maybe you should stop assuming that everyone who disagrees with you is a 'child' and/or coming from a sheltered upbringing. I can tell you from personal experience and the experiences of numerous close friends that addiction

To further the point: what filters would you choose? What features could you choose heuristically to distinguish between the two? They both have fur, they both have four legs, they both have two eyes, they both come in a wide variety of col

I completely agree with you. It just seemed like your initial comment was dismissing the effect/impact of ML because not everyone has the time to learn how to implement it.

I'm not sure I understand your 'cars' comment. The vast majority of people who drive cars have no idea how an engine works yet they are completely dependent on them. 'How' something works doesn't affect it&#x27

The accessibility of machine learning does not affect its impact on society. It already has had a big impact on society whether people realize it or not. It is used for countless tasks that people take for granted (spam filter, facial recog

Image classification is a classic example of such a task. How exactly would you go about writing an algorithm to tell the difference between a picture of a cat and a picture of a dog?

Protons are not fundamental particles, they are made up of quarks and gluons. The exact composition is determined by the nuclear PDF's, it is not nearly as simple as "protons are made of two Up quarks and a Down quark". As a

That's "literally" just how you chose to interpret it. But that's OK as long as it supports your overarching generalizations about the entire field of physics based on a blog post.

Just because you don't understand modern physics does not make it useless. Do you understand how nuclear magnetic resonance works? It's a good thing your MRI machine will still work regardless of your understanding. Do you think m

Although it is a bit of a jab, I wouldn't call it an ad hominem. And this is no way an admission of pseudoscience. She is simply saying that in physics it's (usually) easy to tell when someone doesn't know what they're t

"handwaving problems away with division by infinity" I'm being very pedantic here but it's a bit better to think of it as subtracting infinity from another infinity.

I don't think the author is suggesting that diagrams and visualizations are inherently bad. In fact, the vast majority of physics is done with help of diagrams. Even modern particle physics (Feynman diagrams). I believe the author is p

As a (former) physicist I have to say that there is plenty of eye-rolling about how physics is portrayed in the news. However, in any branch of modern physics it is accepted that no news article aimed at the general public could ever possib

There is a big difference here. In physics, the "outsiders" are easily dismissed. It's just that the outsiders themselves usually don't accept that they're just flat out wrong and convince themselves that it's

That might be true for Bitstrips but not for Bitmoji, which is by the same company as indicated in the article.
