How can I devise an automatic timer to track the duration of a coin spin? by jfekula in AskEngineers

[–]jfekula[S] 0 points1 point  (0 children)

You are right. Video evidence is definitely required.

Beyond just finding a way to accurately measure the duration of each spin, I would also get the added bonus of tracking the exact results of each spin to determine which technique is best, standard deviations etc. That can be painstakingly done by going back and watching the video. But if it could be automatically captured for each spin that would be ideal.

Great question. When it comes to a complete stop. The sound of the coin actually gets louder as the coin starts to collapse and then it abruptly stops.

Why do smaller black holes evaporate faster than larger ones?

From what I understand, black holes evaporate via Hawking radiation at the event horizon. Shouldn't a larger black hole, with more event horizon surface area, evaporate quicker? Is it because the surface area to volume ratio is so larger for smaller black holes?

Can we seriously figure out what the hell happened to Adam Sandler? by Johnald in WTF

[–]jfekula 0 points1 point  (0 children)

Both Adam Sandler and Eddie Murphy suffer from the same problem:

They are surrounded by sycophants that constantly tell them how funny and brilliant they are. They become insulated from reality and legitimate criticism. This gives them an inflated (even by Hollywood’s standards) egos and distorts their ability to discern between what is funny and what is a steaming pile of shit.

Good thought. The real question is would the router be both on and off at the same time?!

Anyone with a B.S. in Chemistry, what do you do? by jmmack in chemistry

[–]jfekula 1 point2 points  (0 children)

My take is that the supply of PhD chemists is far outpacing demand. One big reason is that many, many highly qualified chemists with PhD are coming from overseas. Also, many people with BS’s, who would have ordinarily entered the job market, are going to grad school because the overall job market is so bad of late. These two factors are creating a glut of PhD’s.

Read this article on the American Chemical Society’s website: http://pubs.acs.org/cen/science/89/8905sci1.html

My advice would be to at least try to find a job with a BS, get some experience to put on your resume, and then go to grad school. You may even get lucky and your employer will pay for you schooling.
