I've been hoodwinked too many times by well-reviewed pop-sci books which I later discovered to be hated by the actual scientists who do the work. Quantum Supremacy by Michio Kaku was the final straw 😆

Cheers!

I just watched a Geology Hub upload on the Cerberean Caldera super eruption in what is now Australia. It happened over 300 million years ago, but in terms of the total age of the planet, even 300 million years is a relatively tiny blip. So have there been any significant epics to truly say events like x, y, or z will never happen again – in any statistically significant way? Will there be another Deccan or Siberian Traps or Columbia River Flood Basalts – one geologic timescale day in the future and countless more in the eons to follow?

So Hi everyone, first of all let me just say sorry if u can't get my writing 😭.

I am from pakistan just turned 21 this june. I got very bad hair problems, I'll be attaching image for you guys to look and give me some manly advice without some social media shit like monoxdile, do this, this serum, this mask, this water and sooo on. So I got grey hairs already like 30 40 percentage of hairs are already grey so along with grey hairs i have got these issues: 1: Grey hairs (30 to 40%) 2: I got rough hairs 3: Started baldness if not wrong from front line. My front line hair are not growing well as you can see in the image. 4: I also got mostly dandruff issue but using shampoo like (selsun or selsum blue) or maybe Head and shoulder can mostly control it. 5: I have noticed that i guess my hair growth has been slowed down pretty well. 6: Mostly hair falls when ever i set hairs with my hands, if shampoo, and comb i got hairs falls like hell sometimes

So i need some real advice from people maybe doctors, one with same issues cured or uncured but not other shits.

How to deal with all this. I got pretty hectic routine going to start like night shift and studies so can't focus on routines. I do gym, i got good diet like very very low fast food consumption.

Exactly what should I use or do to make all these things under control maybe with a shampoo or product ? I do oiling as well like there is a oil named Tara meera oil that is like a pepper on a cut 💀 but u know what i want is to get a good hair not a very very good model like hair. Just good hailrs that i can grow, make them long aand style. That's it.

What will you guys suggest. Anyone with suggestions of any kind are welcome to deliver but try to avoid some fake social media and long care products and routine for hair as I can't really afford, as well as can't really focus and do. Most i can do is to oil hairs once a week, do shampoo or maybe conditioner if it is good for hair and use some easy suppliments like Evion that i take already. Tried 60 biotin tablets once from a company called nutrifactor but I don't think i get any results. So yeah this is it. Really appreciate if u guys can share your experience, your suggestions and things works for you. Thank again ❤️

Wherever there is matter in an ever-thinning universe, there might be an entire cosmologically-sized era dominated by an entirely different chemistry to what we have now.

Maybe this should be in Nostupidquestions as I'm aware the moon exists. And I guess there may be an orbit zone where things tend to remain in orbit. But curious...

The full context question is: For man-made satellites, would they benefit by having a "Self destruct" button?

Sure it may add more debris but since an explosion would scatter debris in all directions, anything flung up or down would cause it to get out of this geostationary zone/band.. And hopefully come crashing down to Earth, reducing overall debris? Compared to an abandoned satellite, remaining in orbit and breaking down due to relatively low energy collisions with surrounding debris.

Basically I'm trying to justify self destruct buttons. Thank you!

Are these three statements true:

(1) We can observe where A hits (thereby seeing A as a particle instead of a wave) before B’s path determines the availability of information?

(2) Measuring where A hits, (even if done with thousands of previous data points of A sorted by B hits showing the interference patterns) has no predictive power over whether B’s whichpath information will be erased or not?

(3) Whether or not B’s whichpath information was erased, has predictive power over where A landed?

Theoretically space is infinite, as it is the ultimate container. So how does it expand? For example if you keep adding objects to a room the room isn’t gonna expand, you’re gonna run out of space. So how does space expand if the cause of it is apparently dark matter being created?

I need detailed instructions for converting algae into algenic acid. I would prefer not to use formaldehyde. I am using yellow/green algae so I do expect some adjustments may be needed from brown algae methods.

If we can do plasma deposition for cheap mirror reflective sunglasses with polycarbonate, why aren't these materials commonly used?

If I have a very thin piece of scar tissue on my skin, and then I surgically cut the skin open right along the middle of the scar, and ensure that I do all the best scar healing practises (like holding the skin on either side of the wound together), what will happen? Will the scar get smaller or bigger?

Maybe imagine a can of Rotel mixed in too, which I imagine would be pretty close to water.

I’ve noticed that my queso cools down annoyingly fast, and am curious at what rate it is releasing all of that tasty heat to the atmosphere of my countertop.

I got to thinking last night that theoretically, with enough hair, the air resistance would slow you down so that your terminal velocity would be low enough to land unharmed. How long would it need to be? How would one go about calculating this?

I assume you need some kind of drag coefficient and a density for hair to start with. Not sure where to find that information.

I mean if every variable aligns with any possible edge case that can bleed off velocity including three body interactions with the moon. Is there ever a situation where some substantial (car++) or enormous (skyscraper+++) size rock lands on the surface without explosive energy? Align stars, consult math mediums, play some ZZ Top, piss off Bary the narcissist, or conjure a primordial black hole, just land me a big rock in my yard Science Santa. I want an m-type for Maymass, but any type will do if you can land it.

Why is the spring strengthened in the middle?

It doesn't seem to affect the spring's buckling characteristics.

My speculation is that it's to reduce spring noise. That strengthened region at the middle is where the spring will buckle outwards most, resting against the barely visible side rails on the inside of the case. Instead of just one wobbly contact point it now has three rigid ones as a "skate" to reduce the stick-slip noise when opening and retracting the tip. Is this right?

How does the Moon influence the stability of the Earth's axial tilt and how does this affect long-term climate conditions and seasonal variations on the planet?

It's said that we need sleep because waste products, such as adenosine (which is a CNS depressant) build up in our brains while we're awake. When we sleep, the glymphatic system activates and flushes it out. Too much adenosine is known to cause a slower heart rate, the body temperature to decrease, immune system to weaken, hallucinations, and more.

I read about how a Chinese guy (in 2014 or 2012?) deliberately stayed awake for 11 nights with no sleep at all to watch the world cup, and he died. The articles said he died of sleep deprivation.

Here's the part which confuses me. I understand why too much of a CNS depressant waste product in your brain would be deadly, since it'd supress vital functions such as breathing, heart rate etc. I'm just wondering why it wouldn't make you automatically pass out and sleep, long before it got to that level as it's something which very gradually builds up in your brain the longer you're awake.

My kid got a little round box of soapy solution at the fairground with a wire loop to blow bubbles with. She was pretty excited with it for few minutes, then lost interest. Kept it on her desk when she got back home.

The next morning, she tried to blow some more bubbles with it, but the soapy solution appeared to be as dead as plain water, i.e. zero bubbles came out when she tried with the wire loop.

What kills the "bubbleness" of soapy solution over time ? The concentration of the remaining solution should've remained the same since the box was closed shut overnight.
