Fair enough. I did that because the grammars of Thai and English are quite different, in noun-modifier order, distinction between verbs and adjectives, and verb conjugation (those are just the relevant differences here). I could have said

I've had dengue fever. There are a few different strains and I had one of the milder ones but it was still enough to put me in the hospital for dehydration as an otherwise healthy 20yo. In Thai it's known as hemorrhagic fever, bu

It's an extra-lame counterpoint because male mosquitos don't bite, and they're only releasing males.

I worked on torsion balances, gravity measurements, and gravity gradiometers for my PhD. Getting just a factor-of-two increase in sensitivity is significant--getting 4-5 orders of magnitude better would be incredible and also next to impos

Correction: I missed the year on the linked article. He passed away in 2019, a year before the paper was submitted.

The news article mentions that the student on the paper has passed away. He died of suicide in his lab just a couple weeks after the paper was submitted to Nature [0]. Grad school is hard for a lot of people. Find someone to talk to if y

I like this quoted response: You have reached the required standard, but we are unable to offer you a job immediately. We have placed you on a reserve list from which future appointments may be made. When I was leaving academia it took a

It's unfortunate and potentially confusing to readers that they've used the Washington Monument and the Flatiron Building as illustrations in the article and suggested that their heights might change. The reference point for meas

For those new to geneology, https://www.findagrave.com/ is a great resource for finding grave locations and viewing photos of tombstones.

That's a good reference point. Cost for infrastructure projects usually isn't linear. I've seen an exponent of .6 used to extrapolate costs. (3140km/27km)^.6 * $4.75B = $82B. Adjusting for inflation gives you something

It's a ring, so it should be thought of as something pi 1000km in length, not pi (500km)^2 in area. The inside of the ring is not used for the structure. $32,000/meter sounds pretty generous.

That's an interesting claim. It's true in theory--the information is still there--but what's actually going to do the separation of the noise from the signal?

Whoops, should be "a better ADC won't help."

by mdturnerphys 6y ago
It depends on what the noise sources are. If you're ADC limited, sure, but if you're limited by something else--detector noise, air turbulence affecting the signal, variation in LED output, noise in the room--a better LED won&#x2

That drop in daily new cases is due to a drop in NYC and neighboring areas. When you remove that area the daily cases shows an upward trend.

Adding the second capacitor is equivalent doubling the area of a single capacitor. If you had a plate capacitor where the plates were extendable you could charge it and decrease the energy by extending the plates, which tells you that there
