Wikipedia explains that String Field Theory is a part a of Quantum Field Theory while regular String Theory is not. What exactly is the difference between String Field Theory and String Theory?
541
What is happening at cellular and tissue levels in “muscle knots”?
7285
How can people sever entire legs and survive the blood loss, while other people bleed out from severing just one artery in their leg?
65
I'm reading a book that mentions Nazis were able to determine the weather in London from the hourly broadcast of Big Ben's Chime on BBC. How would a physicist in 1940s find that out?
11
Are there any diseases that affect both plants and animals?
416
Has nuclear testing during the 20th century contributed to climate change, and if so, to what extent?
9
What actually kills a person when their body temperature is too low?
11
This morning I got a cardiac stress test with technetium-99. How is it made?

Ages 1 to 4 are very important for brain development but yet most people can't recall anything from that time period. Why don't we remember our earliest memories?
26
There's no such thing as a perfect vacuum. But what's the closest to a perfect vacuum in nature? In the least dense part of space, how far apart are two atoms?
20
How were steam tables generated experimentally?
4
What determines the phasing of emitted photons?
65
Why is it better for Lithium-ion batteries to be charged after a partial discharge and not a full discharge, unlike the Nickel-based batteries, which had a memory-effect that caused them to hold less charge if they got charged repeatedly after being only partially discharged not fully discharged?
3
How does an object cool in space if it's a vacuum with no adjacent atoms influencing it?
13
With recent advances in quantum hydrodynamic analogue experiments, is deBrogile/Pilot Wave being taken more "seriously" as a valid interpretation of QM?
5
Why do we sneeze, and what is happening during a sneeze?
18
Do the transitions between energy levels of an atom take time?
4
What makes things flammable?
10
What exactly is "horsepower"? Is it literally the power of one horse? How is it measured?
11
How do the activities of nocturnal animals change throughout the year with the changing lengths of night time in temperate zones?
7
Is there an in-depth pathogen family tree (like the animal kingdom tree)?
3
If an object has a low point at which it catches on fire, like 50°F, would the temperature of the flame be relatively lower too?
6
Can you ever breathe so much air that it’s bad for you? If so what about it makes it bad?
3
Why is the maximum density of water achieved at 4°C, then becomes less dense until the freezing point?
1
How are photons "created" from electrons?
3
How does something become radioactive? How are the chemical properties of a radioactive substances different than a non-radioactive substance?
5
Does the color of light change when it enters a different medium?
2
If radiocarbon dating is considered inaccurate for ages >50,000 how do we get accurate ages for older items?
12
Is there a 3D equivalent to the "Four Color Theorem"?
2
How exactly do we determine or calculate the p-value?
2
Is it possible to improve nearsightedness without surgery or contacts, glasses, etc...?
9
Have we discovered anything that can move faster than massless particles? If yes, what and how?
2
can wood fires generate UV rays?
1
Bohr's Model in Regards to Discrete Electron Energy Levels?
1
Where does the term “eye of the storm” come from?
2
What is the electromagnetic "field" around a photon composed of if not a different wave or particle?
1
How can the universe be flat and yet have a radius?
2
Does an increased global average temperature affect geological processes?
2
Does CO2 decrease atmospheric O2?

What's happening on a molecular level when I fold a thick piece of paper and it unfolds itself?

1 petemate I have never heard about wind alone being a factor, but if there is rain, it could very well result in degraded reception.
1 tminus7700 First, there is NO SUCH THING as a 'digital' antenna. ALL antennas are analog devices. For a digital receiver they are receiving an analog signal that happens to be modulated by digital data. Like this: [QPSK](https://www.maximintegrated.com/en/app-notes/index.mvp/id/686) Wind can do two things that could effect the received signal. One is the trees outside get whipped around. They can scatter the signal and depending on the summation of that effect, cause drop outs. Second, the air tends to refract the signal. So wind can wobble the signal path. There is even [summer fading](https://www.google.com/search?q=summer+microwave+fading&ie=utf-8&oe=utf-8&client=firefox-b-1) of signals.
