Does the size of the star have an effect on how many planets form around it, and what size they are?

Pretty much what it says on the tin. Would the planets that form around a K type star be different in size/distance/composition to the planets that form around an A or B type star?

Is tidal locking the end state of all planetary orbits given enough time?

Posted: 06 Dec 2020 08:05 AM PST

I see from wiki that tidal forces depend in a cubic manner with distance so far plants would take an incredible amount of time to become tidal locked. However, given enough time, would all planets eventually become tidal locked (either synchronous rotation like Earth and moon or 3:2 like sun and Mercury)?

What is the REASON behind Joule-Thomson Effect?

Posted: 06 Dec 2020 03:51 AM PST

I would like to know what causes Joule-Thomson effect and why it has cooling and heating effects based on the inversion Temperature.
I am asking for the intra-molecular interaction involved during the effect that causes the surrounding to warm or cool.

Why can't vaccine trials use antibody titers to determine efficacy?

Posted: 05 Dec 2020 04:47 PM PST

I'm going through some school requirements which require both vaccination records and antibody titer results to make sure I'm actually immune. This got me thinking, why don't vaccine trials just use antibody titer to determine if the vaccine works instead of waiting for a certain amount of people to get the disease?

What are we trying to learn from deep learning?

Posted: 06 Dec 2020 01:05 AM PST

What I've read so far is that we are trying to understand how deep learning really works. My questions are 1) what are we really trying to understand 2) what can we do with that knowledge

Does Deep Learning progression usually happen linearly?

Posted: 05 Dec 2020 01:09 PM PST

When a Deep Learning algorithm is progressing, does that progression usually happen in a linear fashion?

Or does it often suddenly make large jumps forward in effectiveness at certain points throughout its process?
