AskScience AMA Series: Hi! I am J.R. Skok. I am a planetary scientist with the SETI Institute and a Space entrepreneur. I am working with SETI and NASA to develop future missions to search for life on Mars, AMA!

Hi! I am J.R. Skok. I am a planetary scientist with the SETI Institute and a Space entrepreneur. I am working with SETI and NASA to develop future missions to search for life on Mars, map out the minerals and geologic history of that planet while leading expeditions to Mars analogs around the world, including Antarctica, Iceland, Hawaii and more. As a Space Entrepreneur, I founded the company, Made of Mars, to develop the technology and economics needed to build things from the materials we can find on Mars, the Moon and asteroids throughout the solar system and share that journey with you!

Proof: https://i.redd.it/vi9rdud0p0t11.jpg

I will be on at 10am PT (1 PM ET, 17 UT), AMA!

If an electron goes around the nucleus in a "probability cloud" and that the electron disappears and reappears in existence, does it mean that the electron appears at infinite positions around the atom or does it just orbit the atom? Also why does the electron not fall into the nucleus?

Why are tyres so wide?

Posted: 25 Oct 2018 03:32 AM PDT

We all know the static friction equation, F≤μ⋅R where μ is the dimensionless Coefficient of Friction and R is the Reaction force of the Asphalt on the tyres.

Note how area does not feature. This makes sense because force R spread over a large area would have low pressure. This would cause less friction per area, but as there is more area to have the force, area cancels out exactly.

This leads me to my question. Racecars, sports cars and special cars like the Formula 1 Williams FW08B all have methods to increase wheel area on the floor, stating increased grip. What is the reason behind these decisions? Is it static friction or something else, like cornering?

Thanks - Oli.

What is the speed of heat? What factors can impact it?

Posted: 25 Oct 2018 01:56 AM PDT

It occurred to me during this annual festival I attend, theres a giant stage with a DJ and pyro technics. It happens this time of year when its cool so just walking by, from a pretty far distance, you can feel the heat hit you as soon as they fire. They just do a short, like 1 second burst, every few minutes. But I can feel it almost instantly. So it makes me wonder, what is the actual speed of heat? We know the speed of sound and light, which this also creates, but how fast is the heat traveling from that flame to my face? How much does it depend on the type of heat? A fire vs in home heating. Thanks.

Why do atoms in electron microscope images always look spherical, instead of p- or d-orbital shaped?

Posted: 24 Oct 2018 10:02 PM PDT

Why don't the microscope's imaging electrons interact or scatter off of the sample's electrons in p orbitals? Or d orbitals? Or any of those other interestingly shaped orbitals I was taught electrons can take? The images always show the atoms as relatively spherical blobs (s orbitals).

What was Planck's intuition behind the quantization assumption?

Posted: 25 Oct 2018 12:05 AM PDT

 First of All, I doubt there has ever been any new idea that did not involve intuition. However, most textbooks suggest that the quantization assumption (Energy can only be absorbed or radiated in form of a discrete quanta: E=hf , and the atomic oscillator can only vibrate by a given discrete quanta of energy) was just a mathematical trick, that Planck introduced to be able to drive his distribution law. Is this the only right way to think about it? If not, did Planck really have intuition behind quantization idea?

How does the body eliminates fat tissue?

Posted: 24 Oct 2018 05:23 PM PDT

I have been changing my life style, eating habits and exercising more. And it made me wonder, how does my body eliminates the fat issue previously stored?

Why are the planetary orbits always presented as all being in the same plane? Are the 8 planets really all in the same plane? Are other planes of movement around the sun expected?

Can antiretroviral medicine be used to treat a broad spectrum of sexually transmitted (say HSV or HPV) infections, or is it used specifically to treat HIV?

Are there any cultures that don't tell their children known fictitious folk tales (Santa Clause, Easter Bunny, etc.)? If so, what are the positive/negative effects?

What are solar flares called when they're on a different star?

Posted: 24 Oct 2018 05:42 PM PDT

What are sunspots and solar flares called when they happen on a star other than the Sun? Both of these names seem specific to our Sun.

How would breaking of CPT symmetry collapse QFT and Theory of Relativity?

Posted: 24 Oct 2018 10:06 AM PDT

Veritasium in this video mentions the consequences if CPT symmetry breaking is discovered. If CPT is found to be broken by particle interactions, then we'd have to reconstruct QFT and relativity theories. Why? and what are the other assumptions for these theories?

How exactly is "turbulence" one of the last unsolved problems in classic physics, and how is it related to the Navier-Stokes equations?

Posted: 24 Oct 2018 10:59 AM PDT

I have read that Feynman said that turbulent flow was "the most important problem still left in classical physics".

In what sense it is a "problem"? Does he mean that we cannot predict turbulence exactly in every situation, and therefore it is considered "unsolved"?

What would it mean for the problem of turbulence to be solved, that we can describe it perfectly mathematically? Or that we can predict the exact patterns of turbulence when any force of any kind is applied to any fluid?

Also, how does this relate to the idea of "smooth solutions" to the Naver Stokes equations?

Have there been any significant changes in political polling methodology since the 2016 election?

Posted: 24 Oct 2018 11:05 AM PDT

As I look at different political polling data for the current election I got wondering if there have been any significant changes in political polling methodology since the 2016 elections. The polling was so off target for the previous election I'm wondering the information I'm looking at now is equally unreliable.

Basically I'm asking what methodological changes have taken place, if any, since the last election? Do we know if the current set of data is more reliable? Also curious as to why the 2016 polling data was so off? Thanks.

Is someone trying to develop electric airplanes?

Posted: 24 Oct 2018 02:37 PM PDT

Planes flying around make up some of the carbon emissions that speed up climate change. Is anyone trying to design electric planes? What are the major issues with them that we need to solve before it could be possible? Is there even a point to try or would it cause some other possibly bigger problem?

What's the most fundamental way we can define temperature?

Posted: 24 Oct 2018 09:14 AM PDT

I had always approached temperature with the definition of being the root mean square of all the kinetic energy in a system, but my physics TA told me that this was actually a rather childish definition, and that a more accurate definition was that temperature was a sum of all the possible microstates of a system, or something like that, which to me sounded more like entropy than the temperature that I knew in real life. Fundamentally speaking, what is temperature?
