In addition to sports and exercising, what is proved or widely believed by the field of medicine that we can do to reduce depression, manage emotion or improve motivation?

I would assume that all the tension in the wire originates from the weight of the mass, and is equal to ##T=mg##, but that is incorrect. Forming a right triangle with a hypothenuse denoted by ##x## and applying Pythagoras theorem: \begin{cases}x^2=y^2+l_o^2 \\ x+y=l_o+\Delta l\end{cases} Solving...

Is it like using the sine rule to figure it out: 1.5/sin 68 = x/sin 17 = 0.47 which doesn't seem to be correct. I tried to determine the angle. I though the 5 degree slope means it could be 95 degrees cause the triangle looks like a right angle triangle.

Hi all, It's a few short months before grad school applications are due, and I find myself in a bit of a dilemma. Prior to my junior year, I knew what I wanted to do is physics research for my career, and I'm particularly interested in biological and condensed matter physics. My skills are more...

I had depression 3 years back and was prescribed anti-depressants which my doctor stopped me from taking one and half years back. I am completely cured now but other problems in thinking do persist. I just don't want to talk on why I got depression on first place ! Though I have good mood now...

Sorry for being annoying, but I am a student of physics for a month now. I started really well by setting up super good work habbits but all was ruined in a day when I was arguing with my parents about my treatment for my desiese. Since then everything has been hell, I fell behind bad, I am...

I began to study mathematics in college because I was fascinated by the subject and have a naturally high degree of curiosity for it along with the rest of the sciences--but stress, depression and other factors take away that curiosity as I progress through each semester, leaving me bored...

When solute particles are added to a solvent boiling point increases, I am quite clear with its explanation (in terms of vapour pressure) but when it comes to freezing point, why does it decrease? What does it have to do with vapour pressure? My textbook says it's because liquid and solid state...

Hello PF First a bit about my illness. I have been suffering from Major Depressive Disorder since I was 18 (I am 23 now). The first few years were unbelievably painful and difficult to carry on, and very risky and dangerous (too many suicidal thoughts, sometimes 100+ suicidal thoughts a day)...

I noticed that my windshield washer fluid has methanol in it to reduce the temperature of which it freezes. I know it freezes at approximately -28°C which gives us a concentration of MeOH at approximately ~30% by weight. However, when I try to calculate the required methanol using the mSolute...

Idk if this is the forum to turn to or even if its the correct forum thread thingy. In that case i apologize in advance. I got no where else to turn to, and I really have hoped to gain some answers somewhere. I have a lot of problems with physics. I'm starting to only now get A's in most of my...

I suffer from serious bouts of depression/anxiety that come and go for no obvious reason. I started physics this year and its hit me half way through the semester. I made a doc appointment to fix this and I am afraid it will hurt me academically if its not fixed and I won't be able to do awesome...

I hope this is right place to post this. I just wanted to get this off of my chest. I am frustrated, and depressed because I am an outsider to the physics community. I am posting this with the hope that somebody else might be able to add perspective to my situation. I apologize if that's...

I'm in year two as a physics undergrad. I have a number of obstacles in my studies, the most prominent one being a physical disability causing severe pain and fatigue, essentially precluding attendance of most lectures. That is something I have so far been able to deal with through planning...

I hate that I am not doing well in physics... I can't stop having suicidal thoughts and I hate it... All I want is to do well in physics and I can't for some reason. I refus to ****ing believe "you're just not cut out for it"... No... Thats not the case... No one is ever just not cut out for...

A man is standing on a 48.5 building and is looking on a second building. The angle of depression of the top and foot of the second building is 50 degrees and 80 degrees, respectively. What is the height of the second building? The height from the foot to the eye of the man is 1.5 m. Hello...

In this thread https://www.physicsforums.com/threads/freezing-point-depression.275386/ in ygggdrasil answer I didn't understand this line This greater loss of entropy leads to a lower freezing point. Please explain.

I want an exoplanet/exomoon with really deep depression. It would be the only place on that planet that's really habitable for humans without breating aid. Idea: -lower gravity (somewhere around 0.8 g) so the mountains should be able to be a bit taller -one supercontinent that's slowly...

That's somewhat depressing...

Homework Statement A hot-air balloon is floating above a straight road. To estimate their height above the ground, the balloonists simultaneously measure the angle of depression to two consecutive mileposts on the road on the same side of the balloon. The angles of depression are found to be...

I was always looking forward to this period. University is finished and work is about to begin. However I ended up getting really depressed. Having found my degree went by fast, I'm not in touch with anyone from college either. Is this normal? I'm applying to a number of backups and reading...

hi guys, need some help for this question. a capillary of unknown internal radius was inserted into a pool of mercury into a pool of mercury. the height of mercury within the capillary was depressed 1.6cm below the free liquid. Calculate the internal diameter of the capillary. For the...

I have tried a quick scan of the web for general information relating to the depression of melting points and found very little available, so i started this thread. The general idea is a depression curve which will help you identify by how much a sample contains impurities. I was looking for...

Whenever I try getting into physics, I get depressed because of all the theories about the end of the universe. Stuff like entropy, ekpyrotic universe (where the universe can end any second), proton decay, etc. Sure, they might be a lonnnnng way off, but it's still inevitable which makes every...

There is a popular claim that the New Deal didn't end the Great Depression; that it only ended because of WWII. 1). How did WWII help to end the depression? 2). Generally speaking, do wars create wealth, and if so, how? If your answer to number 1 is government "government spending", then...
