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?

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?
35 redditoomanytimes Do cuttlefish see the same range colours that they imitate?
16 Chtorrr How did squid become your specialty?
13 Gargatua13013 Hey there Sarah! Glad you're doing this AMA! I'd like us to have a look at the historically important but now extinct orthocone nautiloïds. In paleo classes, they are usually presented to us as essentially "Squids with shells". How valid is this analogy, from the perspective of someone with a strong familiarity and understanding of actual squids, and if that image is not that great where does the comparison break down?
10 KM2000_THE_CHOSENONE Asking kind of a stupid question here. Do the cuttlefish in artificial surroundings have any significant physiological or genetic changes when successive generations are reared in that environment? Like will they lose their camouflage ability or will it be less effective?
10 sexrockandroll What is raising squid like? What sorts of things do you observe about them as they grow? Do they have different personalities, do you form a connection with them at all?
9 jsc32 What sort of immune cells make up the squids immune system? Do they have an adaptive side? Or just innate cells? Thanks! Your work sounds really interesting
8 rxneutrino Is raising bioluminescent squids difficult? Is it something an amateur could do in a saltwater aquarium?
6 aClimateScientist Hi Sarah, thanks for doing this AMA and organizing Skype A Scientist. After a successful first year with 2 classrooms, I’ve just signed up for my second year. Question: Have you heard of “squid mixing” in a Physical Oceanography context? Thoughts? There’s this ongoing puzzle in my field about what’s causing the deep ocean to mix and every once and a while people bring up the idea of biomixing (i.e. mixing due to biomass movements), often jokingly. However, there are some places in the deep ocean where mixing rates are remarkably low (about 100 times molecular diffusion of temperature) and its conceivable that biomixing might be important. I’ve heard rumors of back-of-the-envelope calculations that mixing by giant squid in the deep ocean might actually be significant, because their propulsion mechanism creates turbulent overturns that cause mixing.
6 FreakPirate Hi Sarah. Thanks for doing the AMA. I've been following your experiments since sponsoring a squid (shoutout to Squid Vicious Jr) a while back. I was just wondering how you decided to get into this field and what, specifically, about squid interested you to choose this line of research.
6 themeaningofhaste Wow, you're the person who started Skype a Scientist, that's awesome (so are squid though!). Apologies if you mention these in the interviews but I'm in a bit of an internet rough patch. How did you come up with the idea? How many classes get paired up each week? Any tips for us here trying to do science communication and outreach as well?
5 electric_ionland Happy coincidence I signed into Skype a Scientist last week. What do the squid use their bioluminescence for? Is it a communication system? Hunting strategy?
6 StringOfLights Hello! Thank you for doing this AMA. What would you say are the main differences you've found in working with different cephalopods? Are there differences in behavior and intelligence? They're really interesting animals that have always fascinated me!
4 funfettie hi! what would the results you get from the immune system study be used for? it seems like a very specific study, but i'm sure the findings will be applicable in much larger ways.
3 kitkatcomputercat Hi Sarah! So excited you're doing this AMA! What is the typical life cycle of squids/cephalopods? When do they reach sexual maturity, how long is their average lifespan?
3 thenexustv What do you think of the Cephalopodcast? Do they get their facts straight?
3 cosmicelf With all the fascinating information you possess on Squid, do you see it as an ethical problem to consume them as food?
