Are we producing more atmosphere than we lose at this point in time?

Posted: 13 May 2018 04:14 AM PDT

I guess my question is pretty simple. At this point in time is the planet producing more atmosphere than we are losing to solar wind or are we slowly losing atmosphere?

What are some of the factors affecting our atmospheric production or decline?

Is our atmosphere undergoing any kind of changing state? As in, more oxygen rich, less oxygen rich? Etc....

What are the effects on copper pipes when they are connected to a house's electrical ground?

Posted: 12 May 2018 08:04 PM PDT

In some regions, if a house has a buried copper water supply line, it must be connected to the electrical ground.

How does this affect the copper pipe? I've read frequently that people suspect it increases corrosion, but if only copper and brass are used, I'm not sure how that would happen.

How do magnetic poles spontaneously flip?

Posted: 12 May 2018 01:16 PM PDT

Every so often the Earth's magnetic field flips. What is the cause of this. How does it relate to a small magnet flipping poles? Bonus: In the instant the poles flip is there a instant when there is no magnetic field?

How can I visualize a matrix product with a vector?

Posted: 12 May 2018 12:19 PM PDT

I have trouble wrapping my head around it. For example: say you have a matrix A, vector x, and a new vector Ax=x'. How can I tell what the components of x' stand for? In what way is it connected to a change in basis?

If cancer and psoriasis are both overactive cell growth, what is it that makes them different?

Posted: 12 May 2018 11:07 AM PDT

If you were to compare skin cancer vs. psoriasis they are both described as overactive cell growth, though with different results and degrees of danger. A) how are they different, and B) what is it that makes cancer more dangerous than psoriasis?

Why are the most common screen resolutions multiples of 360?

Posted: 12 May 2018 11:06 AM PDT

There used to be a variety of screen resolutions and different aspect ratios... TVs were 4:3, monitors were all over the place and it seemed like 16:10 might become the standard when HDTV came out and everything shifted towards 16:9.

For a while we had 720p (1280 horizontal x 720 vertical pixels), then 1080p (1080 vertical pixels). Those vertical resolutions are 3602 and 3603.

Some monitors are now 1440p (3604), and 4K televisions are 2160p (3606). I guess poor 1800p (360*5) was unwanted.

Anyway, why are all of the common resolutions multiples of 360? Is it just a coincidence, or is there some reason for it? There were 1600 x 900 monitors, and other 16:9 resolutions are out there. There are a lot of options for multiples of 9 that could have been used... did 40*9 just get to be the lucky winner?

Can the beam quality parameter (M^2) for a laser be less than 1?

Posted: 12 May 2018 10:17 PM PDT

Like the title asks, is it physically possible for the beam quality parameter of a laser to be less than 1? Or is this just not how the M2 parameter works?

What is an intermediate?

Posted: 12 May 2018 04:37 PM PDT

How do we know intermediate steps take place in a chemical reaction if they cannot be measured. Additionally, why are they important in measuring rates.

How would you determine the molecular identity of the ion that is being transported through a receptor activated channel? Have there been any experiments that were designed to accomplish this?

Can you accelerate "virtual objects" above c m/s?

Posted: 12 May 2018 11:25 AM PDT

Couldn't you theoretically make a virtual object e.g. a point on a screen faster than light speed and thus transfer information faster than c? Or imagine a laser pointing at a wall in great distance and the laser rotates at light speed, isn't the point then faster than light?
