Hello, everyone! I find Physics Forums a heaven for me as I can always find what I want here. And decisions to join this group are made a long time after I first encountered the forum. I like math and physics though not talented and suffer a lot from them and nothing more comes to me. However...

Hello!

Hello everyone I'm new on this forum

I have a motor and a 3 phase generator which I would like to connect together, i.e. let the motor drive the generator and measure it's output. Each have their own type of shaft which do not fit together. I would therefore like to get some proposals, preferably which do not require custom work at...

In this thread I attempt to find a closed form solution to the gradient descent problem for a single sigmoid neuron using basic calculus. If you would like to give pointers feel free, if you see me make a mistake please let me know! Thank you!

My second introductory post because we are always learning, right? I am 35 years old with an Associates degrees in: History, Arts & Humanities. I study people and our interactions across the ages and in the present. One of my scientific passions is Geology and Geophysics. Plate tectonics...

Hello, I'm a high school physics teacher and also working on a PhD in science curriculum and instruction. I've been teaching regular and honors physics for a couple of years and probably will add an A.P. Physics 1 section next year (depending on the school's scheduling priorities). I came...

Hi I am new to the forum. I am a investor, athlete, and a "field physicist." I got a bachelors in physics and Hopefully soon can get a phD. I like to do basic experiments that demonstrates physics.

Computation history is cluttered with variants, by-roads, successes and failures. I really like UNIX/C as an engineer and scientist but mainly use Windows for home computing. ##-## @Klystron

I am so curious as to what I actually have found any input welcome please and thank you

Nothing

I believe the users of good old yahoo web mail might guess what this topic is about just by reading the title. I always liked yahoo because it's the only one site I know of that doesn't ask for domain on login. I've had an email address there for quite a long time, but it has become increasingly...

This is my first time idk if i posted in the correct sub

Hey there! This is Mayank Bhandare, from India. I am a recent graduate in Mechanical Engineering from the University of Mumbai. Though it's a strange switch as many would say, I am planning to pursue a career as a Theoretical Physicist/Cosmologist. I have a couple of entrances the next month...

Well we have here a another undergraduate student from Spain (Catalunya) with a lot of questions and any answer in physics. I'm in my 3d year and the next year will be probably studying in Oldenburg (Germany) thanks to the Erasmus Program (any suggestion would be welcome) . I have a lot of...

South Carolina is ready for the arrival of extraterrestrial visitors. On my way to Charleston yesterday, I visited the UFO Welcome Center in Bowman: Nobody was around. Maybe the caretaker was out for lunch? I didn't try to go inside because I might have fallen into a black hole or...

Hello, I had recently created an account. I'm Justin and perhaps am a physics student studying holographic duality and string theory, hopefully my colleagues were right in having me be forming an account in regards to this website. Anyways, pretty much it.

Hey everyone, new to Physics Forums and happy I've found it. To start, my name is Shane, I currently work for Applied Materials. We engineer, maintain, and support tools in the semiconductor industry. I'm 21 years old, and currently on the Global team. Meaning, I travel 90% of the time...

Well, it's been a while and yes I've missed everyone! Got super busy with life and finally able to slow down a little and try to catch up. What all have I missed... Give me the scoop :cool: I hope to be able to stay up to date on and keep active on here.

Hi everyone! I'm really sorry if I'm using the wrong forum. It's my first time at PF. I'm pretty new to physics, as I began studying it just two years ago, but I'm really interested in the subject of astrophysics so I bought myself and started reading 'Introduction to rocket science and...

It's been a while, hasn't it. Life rolls about, priorities alter, sometimes I feel as though I'm accomplishing something aside from absolute decadence, and as a byproduct of all this, I stray from some truly formative sources like PF. I miss a lot of you, and what I remember this forum as --...

Hello , I'm new to this forums so I wasn't sure where to post this , if I have posted in the wrong board please move it to the right section. I always wanted to become to invent tech. I'm amazed by today's gadgets and I love physics. When I was 14 , I told everyone that I will become a tech...

Hello! This forum has helped me solve some tough physics questions already, but I decided to join because I need more help than I've anticipated. Glad to be a part of this community (for the time being and for any future physics classes that I am required to take).

Hi everyone, I joined up today because I was scratching my head for ages about the Carnot cycle. My question was answered in 20 minutes - how great! I'm currently studying to start a PhD in biochem later this year. It means quitting my job and leaving my home behind so I am looking to suck...

I am Mansoor Mirani from Pakistan. I am in graduate in Geography from University of Sindh, Jamshoro. Physics is one of my favourite subject but unfortunately I have not been able to learn it the way I wanted to do it. It think this is the best platform I find for the discussions in Physics and...
