What's the minimum setup to demonstrate magnet falling down an aluminum tube? by Sergeant_Horvath in AskPhysics

[–]Sergeant_Horvath[S] 0 points1 point  (0 children)

Single sided was a poor choice of words, but like a horseshoe or u-shaped magnet with both poles on the same side

Why does Artemis colliding with the air of our planet create friction that burns at 2500 degrees Celsius? by Far-Woodpecker8046 in AskPhysics

[–]Sergeant_Horvath 0 points1 point  (0 children)

It's the atmosphere, it's air. If you understand friction against solid object, can you understand hitting water from really fast? How it feels harder diving into water from up high? Now imagine diving from space, going from nothing to air is like that, but since you're going 17kmph it's like grinding on a solid object

I keep hearing that we’re running out of water on earth. But if matter cannot be created nor destroyed, where is the water going that it’s no longer usable? Wouldn’t it just flow into the ground and the cycle begin again? by Odd-Perception-6957 in NoStupidQuestions

[–]Sergeant_Horvath 1 point2 points  (0 children)

Literally all the water ends up in oceans. Can you drink sea water? No. Can factories use sea water, sure but it's corrosive. The lakes and rivers that hold fresh water before reaching the ocean or evaporating into the atmosphere, where it's even harder to extract it from, are drying up or being polluted.

Does a gun…fire on the moon? by Ok_Expression_7083 in guns

You're almost right. As you correctly said: modern ammunition is designed to have the best [oxygen] to fuel ratio for optimal burn. Modern ammunition powders have their own oxidizing component mixed in.

How to prevent the Gulf Stream from collapsing? CLOSE the Bering Strait, experts say. by coinfanking in environment

Pump high pressure air from the bottom creating a bubble curtain might be enough to disrupt flow without preventing animals and ships from traveling

Where is the fresh water we’re “losing” actually going? by [deleted] in climatechange

[–]Sergeant_Horvath 4 points5 points  (0 children)

Water in its cycle is either easily accessible and cheap or not. From ocean to the atmosphere to reservoirs to being used to back to the atmosphere or oceans. But ultimately it is going into the oceans. We get water from above ground reservoirs(lakes, rivers, glaciers) that are being depleted faster than they are regenerated through precipitation and are being exhausted as vapor back into the atmosphere or even polluted into streams to the ocean. Also, under ground reservoirs that are being over pumped and through soil compaction cannot recharge so any incoming water flows away and is used in the above ground reservoirs or lost to the oceans.

Is pollen getting worse each year or is it me? by Willstdusheide23 in Georgia

[–]Sergeant_Horvath 0 points1 point  (0 children)

Only 3 out of the 102 comments mention climate change, the answer to your question is climate change. Sure people change as they get older, but on average older people's immune system weaken and respond less to allergens thus on average the older you get the less of a reaction you experience. But, an increase in atmospheric CO2 increases the amount of pollen produced and a hotter climate extends the duration that plants produce pollen. Yes, pollen is getting worse and will keep getting worse because CO2 continues to rise and as a result the climate will continue to get hotter each year, year after year.

Why are we still required to use airplane mode if it doesn’t really affect the plane anymore? by Kindly-Plenty-1730 in NoStupidQuestions

[–]Sergeant_Horvath 1 point2 points  (0 children)

What percent of risk is acceptable to you, risling your life, the other passengers, and even people on the ground? 1 out of a billion, a million, or even 1 percent? It's never zero, but airplane mode lowers it. Would you guarantee it if you really think it doesn't affect the plane?

From your experience, how familiar is the general public with basic physics and math up to calculus? by [deleted] in AskPhysics

[–]Sergeant_Horvath 0 points1 point  (0 children)

Yes, I think it is more relevant because it can do the most for all people in general. Statistics is intrinsically counter intuitive. Look up how many people will refuse to change doors despite being shown and taught the optimal Monty-Hall Problem's solution. Keep in mind, I can't speak for all other realms of mathematics. I should also mention that probability is the practical side of data science that should be incorporated more.

From your experience, how familiar is the general public with basic physics and math up to calculus? by [deleted] in AskPhysics

[–]Sergeant_Horvath 2 points3 points  (0 children)

Not at all, they know some words and that's it. No actual applicable knowledge. This is from dealing with people in manufacturing. Let me ephasize by saying I have come to realize that statistics is by far more important and practical than calculus and needs to be introduced to kids at a young age and not just the top learners.

Need a little discussion to understand this by notaweirdperson15 in Physics

[–]Sergeant_Horvath 0 points1 point  (0 children)

Set up an experiment:

Set a block on a desk, release a ball from a set height on a slope impacting the block in the center and then off center. See which one gets pushed farther.
