Yes. PF is a website with policies for each of each of its Forums to match the target audience that is desired by the Moderators. Some PF Forums are homework help where adherence is demanded to textbook and citation references in specialty fields of physics. Other Forums are for professionals...
Safety is my number ONE goal, which is if you walked in on your feet, then at the end of the day you will walk out. I have Zero Tolerance for unsafe behavior. There will be no discussion of the device, just the rare diagnostic needs. It is not a personal project, nor illegal and ionizing...
When looking at arguments involving a spectrometer, one has to wonder if there is not a fallacy in use, by treating the spectrometer as a black box, and not including the numeric output is convertible to a rough approximation of the input.
The series of numbers can be converted back to a...
I read the amount of gold produced cost them around 2 million dollars. So, per ounce of this unrefined gold ore, and refining it, including some radioactive gold atoms, would be like 1 billion dollars per ounce. Making gold this way is not going to get many buyers.
Summary:
I have included some degree of lay person understanding of the word color.
You object. I am fine with your position.
If you want to continue to advocate for all physicists to stop using color names, and do so in Physics Forums, for students and children to learn that the colors of the...
I need to clarify a post I did days ago where I wrote:
This bluish color does not come from emitted photons from orbital electrons. It is from the academic topic called "Art" and its "Color Theory" as perceived by the human brain. Which might be even more complex than what I wrote.
I stated...
I believe there has been a misreading of my quoted sentence. Clarifying posts is important. Pardon the length of this one, as I do believe the details matter.
Allow me to clarify by adding the concept of "color names." Both human perceived and spectrum measured light have color "names."
A...
The fusion type you posted on with He atoms is formally called "Alpha Ladder" or sometimes "Alpha Process." It is the continuation of the "Triple Alpha Process" that creates Carbon from 3 Helium atoms. I am documenting the "messy" details for a project I am working on.
There are over 30...
Rotating plasma is highly abrasive to metal, and any anode in the 'center' will face a material loss issue. At this center the density of the plasma can reach 50 to 100 times of the density of lead. A "center" anode has little chance of surviving, before shutdown is required to replace the...
@jjschwartz1: Your question might be interpreted to be about where color comes from. Or about how atoms have structure, multiple ground state orbital shells with only two possible electrons each, and the nucleus. Other posters added "electron capture" by the nucleus, which is not a process...
I like this question as it bears on 'where' electric charge is 'stored' on the large plate. Or the small. For my answer I assume normal or typical attach points onto the plates of the leads.
What to keep in mind is electrons do not move far to store charge on the surface. Instead of a...
For your paper the academic topic is formally called "Radiation Survivability" for how the Sun's 'radiation' increases the isotopic Van Allen Belt radiation intensity. You will find many papers on it. Around 1986, I wrote the first 3D Ray Trace software for Air Force satellites, winning an 8...
The nitpicking of slight grammar corrections for best value of the thread reader is best done by private email, so the post can be corrected, without adding extra posts to a super interesting thread, that does not involve grammar.
In other words, posting "off charter" and "off topic"...
I continue to learn grammar. It is a life long pursuit. Why? To get to the next level, copywriting.
Also, so I can put in commas, to represent a pause, to let the reader know there is 'time' to think about what was just read, as something different is coming next. I've been told I put in...
