Thanks for the PF connection!

Hi guys! After many years of lurking quietly I finally have a question that I'd like to know, please. I'd like to know how much energy is needed to make a wormhole in terms of our current nuclear weapons, or how much mass is needed to turn into pure energy, maybe via antimatter annihilation...

Hi everybody, my name is Alessandro and I'm a new member here (you might already had guessed that from the title, right?). I'm an engineering student which would really like to know physics better than we are taught, so here I am registering to a physics forum ready to ask question and provide...

Good evening, I am an undergrad biochem student who is probably struggling more with physics and math than an undergrad should. This is my first time on a physics forum, but certainly not my first time on a forum at all, and I generally love the feeling of community that we have in here...

Hi everyone! I am a researcher in nuclear science. I just found this very cool forum and thought I should register. My interested topics are physics, nuclear engineering, and data science. I hope I can learn something new and communicate with everyone here! Thank you! Kochia

Hi, My name is aghbar and I currently live in germany and study computer science. Glad I joined here :) BR, aghbar

Hello I am Stephen and I am trying to become proficient at the maths and physics. I need lots of help. I am not naturally gifted in the math department, although I have come a long ways. I should state that I am 32, although I feel as though I am smarter now as opposed to 15 years ago.

Hi, I’m 28 years old and live in Minnesota. Most of my knowledge about physics is self-taught. (I love knowledge but don’t tend to thrive too well in academic settings for a number of reasons. Kind of like how some people are spiritual but don’t care for organized religion). Anyway, thanks Greg...

Hello, my name is Okinawa Rikenata Aida Islamiyah. I'm now currently studying Physics especially Geophysics in Sepuluh Nopember Institute of Technology Surabaya, Indonesia. Now I'm working on my final project for my bachelor degree.

Good morning to all, My name is Christian Luca. I have a B.S. in chemistry (chemical physics track) from Stony Brook University in NY and a professional science master's in health physics from IIT. I enjoy physics, as well as history, mathematics, chemistry, foreign languages (speak...

Hello everybody I am a medical scientist, more medical and less physicist. I am doing research on cavitation in blood. I have questions on vapor pressure in blood. This is why I am happy to join the group.

Heyyy I am new to this forum even though I have been browsing it from almost the middle of my IB year 1. It is really fun browsing this, and the discussions are very helpful, too! Now that I have problems with my Physics EE I have decided to join this forum. I hope that I will get helped and I...

Just a quick post to introduce myself and to say "Thanks!" for all the answers I have stumbled upon via Google searches. I am retired and spending much of my time reading physics, from Newton's Principia to Susskind's Theoretical Minimum. I look forward to learning with all of you.
