Why is the critical damping coefficient b=2sqrt(km) in a damped oscillator?

Posted: 30 Sep 2019 09:40 PM PDT

Specifically, for the equation mx'' +bx' +kx = 0. I get that b=2sqrt(km) makes the solution of the repeated root form and that it "feels" right, but I haven't been able to prove that this value of b minimizes x(t) (makes it decay fastest) or find a proof anywhere else.

Do hurricanes affect aquatic life?

Posted: 30 Sep 2019 10:29 AM PDT

Their damage to land and its lifeforms is uh.... well very obvious to say the least. But does a category 5 hurricane have dramatic effects on the aquatic life underneath it? In regards to shallow coast lines as well as while it is out in the open ocean?

Thanks!

How is it possible to isolate a single atom of an element and hold it stationary? How is it done?

Posted: 30 Sep 2019 12:40 PM PDT

I recently came across this photo of a single strontium atom, not a real atom but as they put it,

The atom is being illuminated by a blue-violet laser. The energy from the laser causes the atom to emit photons which Nadlinger could capture on camera using a long exposure

https://www.sciencealert.com/this-mind-blowing-photo-of-a-single-trapped-atom-won-a-prize-this-year

So, I was wondering how were they able to separate one atom from, let's say block of solid strontium? And then slow it down so that it can be easily observed?

What is happening in the brain when we try and 'think hard'?

When did the Deinonychus, and other theropods, really live?

Posted: 30 Sep 2019 09:45 AM PDT

I'm doing an infographic project for my design class where I compare some notable theropods to their pop culture counterpart; the velociraptors from Jurassic Park.

When trying to find fact about these animals, I get conflicting information. Specifically with the time period in which the Deinonychus lived, the Natural History Museum says 120-110 million years ago, Encyclopedia Britannica says 145-99 mya, and Wikipedia (yes I know) says 115-108 mya. There are also conflicting sources on it's adult size being 11.4 feet, or 8 feet.

I've encountered this issue with the Utahraptor and Dakotaraptor as well, but not so much with the Velociraptor. I want to be as accurate as possible, but I don't know where to look, or what sources are credible.

I'd really appreciate the help, thanks.

How do they hold together skeletons of large animals at museums?

Posted: 30 Sep 2019 02:54 AM PDT

So my school just finished preserving this massive whale skeleton (see post history) and I'm sitting here studying and start to wonder how it's all held together. Obviously there is significant weight to the vertebrae and head. I know there are a few attachment points when they're hung up but it doesn't seem like enough. I'm just wondering how it's all held together but Google is coming up dry!
