They prove a new upper bound to a combinatorial quantity that controls the worst-case running time of an algorithm of Dadush, not an upper bound to the optimal value of a given ILP instance. If they wanted to see their ideas work in practic

The exponential curve does look like a line when you zoom in very close to a point. For example, f(x) = e^x looks linear with slope e^x near x. You can see that, for small epsilon, e^(x+epsilon) - e^x is approximately epsilon e^x, with an e

The analogy would be that if your friend Bob asks you for a $1k loan, you could tell him "done, I am loaning you $1k and for now I am keeping it safe for you; just tell me when you need it". Now you have all the money you had befo

You can see that the market deviates from the model and accounts for the fact that the Brownian motion model of Black-Scholes underestimates the probability of big moves: typically, options for the same security and the same expiration date

I don't know if it's still there in the revision, but in chapter one of the earlier draft of the California framework it said, in a prominent place "we reject ideas of natural gifts and talents" Edit: in the new version

If one player picks 50 of boxes, the probability of finding a particular number will be 50% independently of the strategy. (Note that sum([1.0/(100-n) for n in range(70)]) is more than one: the probability is 1/100 + 99/100 *

I am feeling really dumb for asking: the punchline of the comic is clearly that there is something terribly wrong with the typesetting of the business card, but what is it?

This is not exactly how fractional reserve banking works. I think that there is a misconception that if, for example, there is a bank regulation that allows 10% fractional reserve banking, then if a bank has $1 million in deposits (of actua

$200k is your expected equity payoff if you have a 2% chance that your equity is going to be worth $10M and a 98% chance that it's going to be worthless, which is the simplified model used in that back-of-the-envelope calculation
