adding up to zero. Likewise, it seems like it should follow that there would have been equal amounts of matter and antimatter created. But if that was the case, it would have all been annihilated, leaving nothing behind but a titanic flash of light. So why is the Universe full of matte...
So, while it’s hard to say with certainty what a “good” score is in absolute terms, you can get an idea of how your score stacks up with all the other GRE test-takers. The higher the percentile, the more people you scored higher than.More important, though, is what a good GRE ...
(Left) as the sphere grows, the number of points from the line that it contains increases like R, so the line is one-dimensional. (Right) as the sphere increases in size the number of points from the rectangle that it contains increases like R2, so the square is two-dimensional. Ho...
then that thing is behind you (physics is full of profound truisms like that). Special relativity has provided us with another kind of “rotation” that exchanges some of one of the space directions with some of the time direction, but in a not-quite-as-simple way that involves ...
Everyone knows that C is efficient because it handles the server hardware more directly than a higher-level language like Java or Python. So programmers expect Currie and her co-authors to tell them to go use it. But it’s not that simple. ...

A decision is madeafter the photon has passed the slitsabout whether to observe which path it took. If a detector is placed to determinewhich slitthe photon passed through, it behaves like aparticle—no interference pattern appears. If the experiment is set up so that no which-path informatio...
Finding 3:A reasoning model that uses more tokens for a given problem is not always the most accurate one.Even for the same model, longer generations are on average less accurate than the shorter ones. There is high variability in token use, even across models wi...
However, who/what is information is led to be judged by the average joe, which only confirms the Dunning-Kruger curve, and IMO this in turn facilitates echo chambers by marking individual comment(trees) as "BS". It leads to a lot of unfair moderation as anyone can vote(just like Reddit...
