Science Definition and 990 Threads

How the physics and science limit our cosmos observation and link it to speed of light? I could not find any equation, study or science that can support and limit our observation parameters.

Always looking for answers. Wanting to help my students discover the curiosity about the world. Would love to enable a desire for understanding all around us.

I would like to subscribe to a general science periodical (emphasis on physics would not go amiss) other than Scientific American that would explain new scientific discoveries and ideas in popular terms. A hard copy magazine best but digital okay too. Please, no defense of Scientific American...

I don't have much to say, at the time I had to drop out of university but I've always been passionate about science and I can't stop reading and thinking about it, especially physics and mathematics.Welcome everybody.

Can I do a Master in Biophysics after a Bachelor in Electrical Engineering?

I'm a student at a community college that was gifted a wind tunnel by a local uni. I'm leading a group of 5+ engineering / science students to refurbish and tune it. The testing chamber is around 12 x 5 x 5 inches, and we have free reign to do anything we'd like. We've had some ideas like...

Since these two pillars of science have mass as a common core, are they related, essentially the same or not?

Hello. Thanks for having me. I'm Paul, from the UK. I'm interested in physics, and maths, and science generally, but mainly physics, and within that mainly cosmology. I'm maybe around GCSE level regards maths and physics, roughly high school diploma level in the US, according to Google, although...

Can you recommend me a source to self study computational materials science? I am currently doing an internship and want to study in my spare time for materials science. I will take a course named computational methods in materials science but I want to learn it earlier than that but I can't...

Kyle Hill has done a rough analysis of Youtube Science channel content and says that there is a spam problem at Youtube where folks are creating content at an astonishing rate of poor quality science videos for monetary gain.

Hello, I am a manager at a non-profit science centre. I manage a team of educators that develop and deliver STEM programming to students all across my province, with a focus on science/coding/technology. I am passionate about teaching, and I aim to find ways to integrate all of the scientific...

Greetings, I am here to "brush up" on my general physics knowledge and more as a life long learner. My background is in biochemistry, but I believe in being well rounded as a scientist, a student and a educator.

I have always wondered about this: Why is it that at US-universities the ratio of subject matter courses to general education courses is so much lower in science programs than in engineering programs? As if there were not enough material in the sciences.

As you may have noticed, I am obsessed with understanding the difference between two views of quantum mechanics, one of which can be called the "standard" view, and the other the "realist" view. The difference, of course, is very complicated, but I believe that the essence and origin of the...

I subscribe to this forum because I like science. I think science is the future and I don't know why but I think that time travel is possible with science. I looking article about this subject and this is amazing. I want to learning more about time travel and other science subjects. Thanks for...

Hey! This is Jasmine Masown here. A curious learner, book lover and a science buff. I've been passionate about science and how things in our universe work ever since I was a Lil kid. Hopefully carrying that love for science forward in the form of formal education (physics undergrad). Thank you...

I started my research in statistical digital signal processing two years ago, so I need to familiarize myself with all the notations people use in probability and statistics. I come from a deterministic science background. I name my variables based on what they mean. A velocity is a v , a...

Today I learned that once again a Star Trek story is soon to become fact: In the story of the M5 computer, human engrams were used to augment a new class of computers to supercede the duotronic ones on the starship Enterprise. Now in real life, we have one based on mouse cells...

Wasn't sure where to categorize this thread, but thought chemistry would be the most appropriate (mods: feel free to move as you see fit). I have some questions on the science of water evaporation - first in general terms and then within the context of something that happened to me. General...

Hi again all, hope you are all doing great and enjoying the spring as well as nice weather. This is sort of a continuation thread of my falling in love thread here that I posted a while back but with a new question witch is: Can I get the same effect to live longer by falling in love, having sex...

i made a comment on youtube = It's only 4 minutes long, see the last minute If Jim went away at 99.94 c, for 10 years, and we see him take 29 years, 1) what doe's that mean, it means that Jim's apparent speed from Earths veiw has to be slower than 99.94 c, because it took longer, it equals...

Earth's distance from the sun is said to lie in a small Habitable Zone (HZ) . How did it come to be in such a fortunate position? It seems that someone in the past could have asked this question and concluded on the basis of anthropics there must be a large number of planets in our galaxy. My...

So for this question, I understand the math but just wanted to be clear on a few things. So I had this question on my midterm but instead of tensile and compressive stresses, it was tensile and tensile stress. I initially thought that the delta sigma in the integral was the maximum stress so in...

From where I stand, human evolution from primates is more evidence-based and storied than our understanding of bats. Do we have an evolutionary understanding of bats? Or are their origins still more myth than science?

In my late twenties, currently working as a data scientist in the UK, looking to sit A level maths, further maths and physics as a private candidate (not going through a distance learning provider) and pursue a joint degree in physics and computer science (which I know both St Andrews and...

I am currently a sophomore in HS, and I have a science fair project next year. I want to do something interesting- I don't want to put in barely any effort and do something that everyone has done, like 'growing plants in different light levels'. I would ideally like to do something with...

My thread "Space-time quantization and its philosophical aspect" was closed. Can you suggest other science forum where I can create such threads? I have many ideas of this kind, and I want to initiate conversations about them. And what forums support the discussion of new ideas and hypotheses in...

I’m in need of recommendation of a general science book (‘general’ means just a bit of introduction and its application, not going into its detailed theoretical and technical workings) which contains the following topics (though not exhaustive) Space Technology: the basic concept of launching...

I'm looking for a list of commonly misspelled science and math words. What do you see often?

I 'v worked as a physics teacher in a famous senior school since I got my degree in 1996. And, reading is one of my loves.

Hello everyone! I have a question about a potential flaw I see in the scientific method, but I hope people will illuminate me, and convince me that science has no problem in the respect I might lament on. What if a scientific premise in a deductive argument is based on an observation, and we...

I am currently a final-year undergraduate student whose primary major is Physics. I double major in Computer Science, and my grade is currently near-top in my department from a prestigious university (non-US, top in my country). My research experience during undergrad has primarily been about...

So, I'm not on twitter but I just heard Sean Caroll say on his podcast that he's following science journalists on twitter and that he uses that to know when something interesting happens in science because these journalists will link to it. Do some of you do that also? I'd like to know who you...

My name is Joe, I'm 36 years old and currently between work. I live in The city of Erie, Pennsylvania. My interests are in the phields of electricity, physics, chemistry, and all engineering principles related. As I am only a high school graduate with no formal training, my education is self...

If you enjoy both physics/science and history like me, you may enjoy this video from the Royal Institution. It's about groundbreaking experiments (no theoretical physics); X-rays, particles etc. I'm only 45 minutes in so I haven't seen the entire video yet, but I wanted to share it...

I just read Feynman's The Value of Science and really appreciated his perspective. We generally value art, literature, and poetry but if you want to do science for the sake of science people take offense. It takes years to build a foundation before you can appreciate it, so the general public...

When I went to college, more than 30 years ago, as far as I can remember, nobody was talking about the use of Occam's razor in science. Reading the works of past scientists, I rarely see them invoking principles of parsimony, let alone cite Occam's razor. Yes, Newton, Einstein, and few others...

I am currently in my final year of high school in India, and slightly confused as to which course I should take. I've always been interested in physics, and would eventually like to do research in quantum computing. I'm not sure whether to take a B.S. in Physics, or engineering (a BTech) in...
