How do we know what dinosaurs ate exactly if only their bones were fossilized?

Posted: 21 May 2018 10:41 AM PDT

Without their internal organs like the stomach, preserved or fossilized, how do we know?

Edit: Thank you all for your very informative answers!

Why does a hydrogen bomb need deuterium (aka heavy hydrogen) yet the sun does just fine with regular hydrogen?

Posted: 21 May 2018 11:51 PM PDT

If the neutron in the deuterium atom is needed to sustain the chain reaction in a hydrogen bomb explosion, why isn't it needed in the sun?

What research is currently being done to help cure the HSV-1/2 virus?

Posted: 21 May 2018 10:39 AM PDT

Not sure if this is the best place to post this, would be happy to delete and post somewhere more appropriate

What research is currently being done to help combat the HSV1 and HSV32 virus in humans?

Why is it hard to find a cure for this illness?

What are the limitations in what can be done, chemically speaking when it comes to medicine for it?

Do amputees produce less blood than the rest of us? Or do veins/arteries "stretch" to fit the extra volume?

When conducting a dual-slit experiment, what kind of sensor can detect photons without preventing them from passing through the slit?

Posted: 22 May 2018 01:29 AM PDT

All the photon detectors I'm familiar with would occlude the slit in order to measure the photons that would pass through that slit. In this case, though, by adding one of these, aren't you basically back down to a single slit?

Why is it that the ratio of men to women is rather uniform across humans?

Posted: 22 May 2018 12:37 AM PDT

Why is it that there is, with some variations due to war and such, generally speaking a near 50/50 distribution of men to women in humans when it would seem that due to the way reproduction works having more women than men would be beneficial?

Also on a side note is there any crazy variations on this distribution outside of countries with less men due to war? Do other animals also have similar ratios?

When two objects transfer electrons through friction, what determines which one receives the majority of electrons? In other words, what determines which object becomes positively charged and which one becomes negatively charged?

Why do all of the planets go around the sun in the same direction and what would happen if they went the other way?

Why isn´t it possible to calculate the energy which the laser emits on the particle and know both: momentum and position? Would this make 'seeing the future' possible as you know both now?

Posted: 22 May 2018 05:26 AM PDT

Due to Heisenbergs uncertainty principle we cannot know position and momentum both, due to for example a high energy laser messing with the momentum of the particle - if I´m not correct here please tell me, im not a physicist in any way Im just curious.

Is there a difference between natural sleep and sleep via medication?

Posted: 21 May 2018 02:42 PM PDT

Does your body heal up the same way? What about cognitive ability? Is there actually a difference from when you fall asleep naturally compared to taking a sleeping pill? Or even getting black out drunk?

1 Can anybody who knows psychology explain to me what is going on when people experience serious mental block in front of a camera?

Posted: 22 May 2018 12:50 AM PDT

I am talking about this https://www.youtube.com/watch?v=wJdNrCeUdhc And let us ignore the point Kimmel is trying to make. I refuse to believe that so many people are not able to name a book when asked in front of the camera. Even if they don't read, I'm sure those people could have come up with an answer if asked casually by a friend. So what is actually going on? Is it some form of stage fright?

As Li-ion batteries age and hold less charge, what actually changes about them chemically?

Posted: 21 May 2018 02:34 PM PDT

And, when these batteries reach their end of life and are disposed of, can they just be sent back to the factory to be melted down for raw materials and turned into new batteries, or would additional material inputs be needed?

Why is Neoprene more resistant against ozone?

Posted: 22 May 2018 01:11 AM PDT

Why is Neoprene more resistant against ozone than regular rubber (latex)?

Regularly, I think that the dubble bonds in the rubber polymers burst when they react with ozone, so that the whole rubber eventually ruptures. This doesn't occur to the same extent with Neoprene (polychloroprene). Why? Does it have something to do with the chlorine in the rubber, that the chlorine reacts with the ozone instead of the dubble bonds? Please explain!

What is mesons role in Standard Model?

Posted: 21 May 2018 08:48 PM PDT

Standard Model tells us that quarks are the building blocks for hadrons (i.e. baryons and mesons), baryons in turn are those for atom's nuclei. Earlier they considered mesons as mediators for strong interaction, but now gluons are the ones 'responsible' for. So, why mesons are still important?

Is there an equation predicting the Hooke's law constant for a simple spiral spring based on: the material and the spring geometry?

Posted: 21 May 2018 11:47 AM PDT

I have been using my 3d printer to print simple springs (the common spiral kind, not sure of the name). And I can test them to work out the [k constant](https://en.wikipedia.org/wiki/Hooke%27s_law#Formal_definition) (k*Displacement = Force). Is there a general equation where you just put in (I assume): a material property, the height, the width, the thickness of the spring coil, and the number of coils.

EDIT: Thank you u/nastienate15 for catching my typo.
