I am researching physics to help others
I am a student pursuing a master's degree in physics.
Hi Gary, I am responding to your closed forum: Like a claw fossil or something. Your picture is upside down. Clean up your rock with a steel welding brush to remove the mineralized dirt and oxidation. This will bring out all the colors. I can see from your photos that the inside of this rock where it is exposed is agatized. A product of fast fossilization. From what I can see, you don't have a claw, rather, you have a turtle's front flipper. Hope this message finds you. Greg

Hi Greg, and Welcome to PF.

Gary has not been back to PF since 2009, so it's pretty unlikely that they will respond. Thanks for trying though.

Started studying rotational motion today. I wonder what I should focus on.

Ah, so that means you are using vectors and calculus in the calculations of rotational motion, Moment of Inertia, precession, etc.?

This is one of the solutions of our electromagnetism CA test. I did not posted the question sheet. That Q3a says "from microscopic view, show that current density J (J=I/A) can be expressed as J = nqVd."

I admire your username. Your profile pic. And the content of your posts.

Hello,

You should start a thread a new thread. I think what I wrote is incorrect and needs revisited anyhow if you have a similar question.

Whew, another anime enthusiast? What is your favorite anime, bro? Mine is YuYu Hakusho or Hunter X Hunter, along with Studio Ghibli.

That is good. It is always good to see someone into anime. Hunter X Hunter was the first anime I have ever enjoyed in November 2021. :) One Piece is also good, but that anime goes on forever, it seems.

Hi Borek. Is there something up with Chemical Forums? For the past week I haven't been able to connect, just get this error message. Applies to both laptop and phone. Any help appreciated.

Yes, there is a serious problem. Since Saturday site is under slowloris attack (kind of a DDoS attack) and it had to be switched off to not interfere with other VMs residing on the same physical computer. I am in contact with the provider, sadly at the moment there is nothing they can say about when the site will be back online, as the attack continues.

Thanks for the feedback, good luck with getting it back online.

Hi Greg,

I've been checking those threads nearly every day for years.

Do you think I should check more often?

New here. Do not have a background in physics, but do want to learn more. Hoping for a friendly experience here.

Hit the last nail in the coffin. One more exam and I am out of academia. End of a dream, or maybe I was just daydreaming?

Thanks. Though it would have been nice if I could pursue Masters; ending the academic life at graduation wasn't exactly what I wanted. But then, life doesn't always go the way we want it to, does it?

fwiw I interpreted these other Ibix statements as meaning that someone here has to be able to look at both clocks, not that the clock at the BB last scattering itself also needs to be able to see our clock here. I am still not sure why it needs to. Perhaps Ibix should try to be clearer.
I enjoy Cosmology, but I only get a few hours a year to read about it. If you want to know anything about RF engineering you let me know

I will add that I hope that we will learn the truth about the age of the Universe and find consistancy with formation time of Galaxies. Some are saying Cosmology is in crisis and to be fair there are a lot of speculative theories now out there confusing the public. Just today, I saw white holes being created from black hole bounce in secrets of the Universe on Science channel.
Did you find the bed you were looking for, because if you didn't, I know where you can find what you need.
Hello Vanadium 50 - this is my first time using this forum, so I'm not sure if I'm doing it correctly. I wanted to see if you'd seen my message from yesterday. I found two separate sets of conflicting data related to one of your old posts, and I am trying to understand how to reconcile the two - perhaps how the data was re-tabulated somehow? Thank you for any time you have.
Sorry for being 4 years late, but I read your thread about what you wanted to major in and I think if you like biology, chemistry and physics then go for chemical engineering, and then later you can work at various companies (like NASA) since you like aerospace. You could also minor in computer science along with this since you are interested in robotics/AI-related stuff.
Passionate about math but can't understand science for life's sake :/
Hi all,
I want to determine the lattice parameters (a, b, c and beta angle) for the thin film of a monoclinic system from the thin film XRD data. I have HRXRD data of epitaxial/oriented film. Is there any program or script to compute the lattice parameters?
Thanks

Welcome to PF.

For general technical questions, post them in the appropriate technical forum (start the thread by filling out the form at the top of that forum) and include links to your reading that you've been doing and ask questions about that reading.

For schoolwork-related problems, post in the Homework Help forums and fill out the Template that you are provided there when starting a new schoolwork thread. That includes the Problem Statement, the Relevant Equations, and your Attempt at the Solution. Always show your work on the problem so that we can then provide tutorial help.

Congrats on the new Science Advisor badge. Very well deserved, and we appreciate your high quality posts here. :smile:
