We've reached a point where it seems like you can't be an expert in everything. But it seems from history that there was a time when you could be good at all the latest research subjects. Over what time period did those changes happen and what changes happened for such a shift?

Or maybe even talked to someone who doesn't do science but has an interest in the knowledge? How was your experience?

I'm filling out a form and I'm required to give the following information Mailing Address – In Care Of Address Line 1 Address Line 2 City/Town District/Country/Province/ State Postal Code/Zip Code Country Now, I have two questions: 1) What does "in care of" mean? Is that supposed to be my name or the name of the owner of the house or the name on the postal box? 2) What goes into address line 1 and what goes in 2? I just have a street name and number and I live in a house, I don't need 2 address lines. NOTE: This is an American form, so I need answers from folks from the US. I think what address line 1 and 2 are might be diffe…

It seems to me that whilst feet and toes are not as dexterous or strong as hands they are still capable of gripping and holding - and that would be useful in zero gravity. Those with no choice but rely on feet show how versatile feet and toes can be with practice. Down here on Earth I will use my toes to pick things up off the floor and pass them to my hands when I am barefoot, usually without conscious thought. I think not using feet in space is a wasted opportunity. Should astronauts be training to use their feet and toes to maximise their body's versatility?

Since Greta made her speech to the world leaders, my facebook feed has been littered with angry adults, including friends I'd previously considered intelligent and conscerned with climate change, trying to discredit her with various memes (below is particularly stupid). https://metro.co.uk/2019/09/28/jeremy-clarkson-brands-greta-thunberg-spoilt-brat-shut-get-back-school-10823793/ https://www.independent.co.uk/environment/greta-thunberg-trump-latest-threat-climate-change-un-summit-speech-a9121111.html Frankly, i'm embarrassed to be an adult.

What is your fav alien invasion novel, series of book or even short story and why? Mine is https://en.wikipedia.org/wiki/Worldwar_series It is unique and hauntingly realistic IMHO!

I am very sorry about my past behavior and would like to be apart of this fantastic community again :)

I am an IT professional and a huge SciFi fan. I started working on worldbuilding a science fiction universe that I believe is scientifically plausible, while trying to include any inevitable technologies and capabilities and avoiding theoretical physics longhots like negative energy, artificial gravity, wormholes and warp drives. I've been learning to 3D model in Blender and working on making a 3d animated series for YouTube. I wanted to show viewers a future that might actually be possible instead of the scientific surrealism of Star Trek or the many other SciFi universes that have one more more elements that are definitely not possible that bring their entire house of c…

I want to include a glossary-like appendix into one document I wrote (basic-level overview of magnetism). I planed to include a chart at the beginning of the glossary to depict relations between explained terms. It proved harder than expected. I have doubts about almost everything... Maybe you want to comment or advise. The idea is not to provide rigor, but to provide some orientation. Here is what I have so far:

I wasn't aware that there is currently an EU tariff of up to £60 per kilogramme on US cheese. I really would like to taste some of the good stuff- any recommendations? https://www.bbc.co.uk/news/world-us-canada-48915578

What is the point of withdrawing from a check while receiving clearance if one has committed a heinous crime? From what I have discussed with some friends, once someone is denied, they are blacklisted from clearances. Someone in such a situation, would they have anything to lose whether they withdrew or not? Just morbidly curious.

As of September 2019, these are the 5 potentially habitable exoplanets closer to Earth: SPAM DELETED 1.GLIESE 273 b Gliese 283 b orbits the red dwarf star Luyten, located 12 light years away. - The exoplanet is 84% similar to Earth. - It has an orbital period of 18.6 days. - A minimum mass 2 times higher than Earth. - An average radius 40% higher. - And an equilibrium temperature of 11 degrees more. 2. TEEGARDEN b Teegarden b orbits the red dwarf star Teegarden, 12 light years away. - The exoplanet is 95% similar to Earth. - It has an orbital period of 5 days. - A minimum mass and averag…

Nowadays a lot of people like to fashion themselves in a way that is less traditional. You might see men wear make up or men and women coloring their hair some color that isn't naturally possible. Since society is so free, even among serious scholars (as I see in my department), what is the point of having a strict dress code? I imagine one doesn't want someone showing up scantily clad or maybe there is a uniform requirement to represent a certain party or for a certain type of job but there doesn't seem to be much point for specifying such at social events in places such as conferences.

I was talking with family about a friend's upcoming wedding, and I put forward the idea that instead of the bride spending BIG money on a one-time use wedding dress (no, your daughter probably won't want to wear your old one), while the groom rents a tuxedo, it would be a much better tradition to buy the bride either a sharp designer outfit for business or a designer dress she can wear to fancy occasions for the next several years. Buy the groom an Armani suit and he'll have something fantastic to wear for quite a while. Horrible bridesmaid dresses could be a thing of the past. Of course, this assumes you're not already wealthy enough to spend thousands of dollars on…

Just found science forums evil twin, suppose everybody has a doppelgänger.. https://evolutionfairytale.com/forum/

I read today that some samples retrieved from Moon by Apollo missions were sealed and never examined. Is this true? What is the rationale for such decision?

If you had the power to create or change one law, what would it be? I've posted in the lounge (for a bit of fun) so feel free to be creative. Here's a starter for 10: Any money spent lobbying the government, for whatever reason, must be matched and given to their opponents.

... when you check out a book on an rfid self-checkout machine in a library. I assume it has something to do with an electromagnetic field, but does anyone know more?

You probably don't have to have a sense of humor to be conscious, but it helps. In the tv series Trailer Park Boys Julian, the mastermind, is in jail and Ricky and Bubbles have the people in the park growing vegetables. Bubbles uses the veggies to make spaghetti sauce that he sells at the flea market. A guy who owns a chain of restaurants offers Bubbles a wad of cash for the recipe to his sauce. Ricky says SELL but Bubbles says no, what would Julian do? Ricky answers "probably something stupid like supply the restaurant chain with the sauce". Bubbles says awesome idea and makes the deal and even more cash. But Ricky is bummed. What's wrong, Bubbles…

Niel Degrasse Tyson posted this video. He mentioned aliens taking packages out of our closet and moving them to another dimension at 1:47. Does this mean that popular science thinks that aliens could be living in a 4th spacial dimension?

This is just for my amusement... There is this "Maxwell-Faraday equation". I was thinking is there any scientific formula or law or a thing that might include two stronger names? For example, is there something like Einsten-Newton stuff in physics, or something like Euler-Gauss stuff in mathematics?

I cleared out some junk and stumbled upon an early attempt at doing “science” with math and observations to get some result. I used a cheap monocular to project a partial eclipse on a paper, the goal was to measure how much of the sun that was covered. I remember getting help with the math for intersecting circles, we had not done such geometry (yet) in school. Do you have any early memories from attempting something scientific? A fun aspect of this little experiment is that I think one can get decent precision even with cheap equipment. In the age of internet I might try to locate data* from this event and see what the real value was. But my skills at ob…

Same even with immortality, is question: 1. if you get transferred into computer 2. or die and copy of your mind gets transferred Even even if so, what if someone kills you, or you die by accident, if you mind will be backed up and than copied to new body, it won't be you, but your copy. Even if you was lucky and lived like 10k years, eventually you will die anyways, even universe is probably going to end and it will be difficult to survive... Same there is no point, why would you do that ? So you can live another x years for what ? And it is so boring, everything is predetermined, or random, which is not any better... So you maybe explorer new planets…

Is there a place on the site for videos like this and if not should there be?
