Welcome to /science/, the board dedicated to the discussion and fostering of mathematical and scientific ideas, phenomena, history, and understanding. Any content related to science or mathematics is greatly encouraged, whether it is HAM radio operating, hacking, psychological warfare, weaponry, construction, chemistry, or anything else on your mind. It is highly recommended to study, learn, and form an understanding on mathematics, physics, and philosophy as they are the foundation for almost all fields and will heighten your understanding of the world around you and will make your critical thinking and analyzation skills greater.

Then, gradually apply power to the flyback. If all is well, the electrons hit the target and X-rays are produced. (I just realized this seems more like a tutorial than a question.) For anyone wondering about the legality of this, the production of X-rays is relatively simple.

⛔I know this is fucking dangerous⛔ It's only theoretical

on the model of a 12" monochrome CRT television

Steps:

Remove the electron gun:

Open the television, take out the cathode ray tube, being careful not to break it.

The electron gun is in the neck of the tube; remove it.

If the filament is broken or old, replace it with a 0.2 to 0.5 mm tungsten wire.

Hold it firmly, so that it doesn't touch other parts.

Assembly in the vacuum chamber:

Place the gun in a thick glass jar.

Place the metal target inside, about 2 cm from the filament.

Close the jar tightly and connect the vacuum pump to 1.33 x 10⁻⁶ atm.

Electrical connections:

The filament is connected to a 6.3 V source, with sufficient current, assuming With a 3.5Ω resistor, we would need to apply 1.8 A, but resistance increases with temperature, so a better approach would be around 0.7 A.

The copper anode (tungsten would be better) (metallic target) is connected to the positive side of the flyback (high voltage).

The cathode (metallic structure that holds the filament) goes to the negative side or ground.

Startup:

First, turn on the filament; you should see a faint red glow.

Then, gradually apply power to the flyback. If all is well, the electrons hit the target and X-rays are produced. (I just realized this seems more like a tutorial than a question.) For anyone wondering about the legality of this, the production of X-rays is relatively simple.

Going to be fixing the board later and going to add some resources to learn.

Education in the united states is very much a joke in this day in age. High school could be considered a daycare for teenagers and college and university will cost you thousands for knowledge you could get for free in a library or on the internet. NASA is already difficult to manage as the space race, believe it or not is still going and the first country to build a moon or mars base is going to raise some eyebrows and is going to make tensions between countries worse. Organizations such as SpaceX are pushing space colonization for private companies and putting the government agencies in the dust.




Creationists lose again.  Soon we will be able to  explain how life began. The god of the gaps is becoming a very small god! Today worshipping  god is little different from worshipping a toilet and praying that it won't stop up, and will magically take your shit away because you don't understand how the plumbing works.

> Much of the world was introduced to the platypus in 1939 when National Geographic Magazine published an article on the platypus and the efforts to study and raise it in captivity. 
>  First published in 1888, in 2015 Fox assumed ownership.
How could they let this happen? Good men would never sell their stock to an anti-science media empire.
> Scientists find a mammal that lays eggs
> Clearly it's in between a bird and a mammal
> Theists insist evolution isn't real
> Say this ugly racemixing creature is intelligently designed by God.




Everything should be free and open source. Did the caveman patent fire or did he give it away for free?!

There are correlations between having a dick and being rational. Maybe this next part hasn't been proven, maybe it's being proven, but a positive correlation for Testosterone is likely. 

What we do know is that testosterone levels decline with age, which correlates with stupid, grumpy, and stubborn old grandpa. Testosterone calms you down which is important for clear thought; we've proven it reduces anxiety by injecting male and female mice with two doses of it: HTTPS://www.ncbi.nlm.nih.gov/pmc/articles/PMC4330791/

Science is wonderful, but there are still many unanswered questions in dick science. What genes affect dick length and pleasure, and can we know how to genetically engineer a change in vitro? Can we know why are masculine women and transsexuals so angry, and why do they want to destroy all dicks? Did testerosterone deficiency cause Sam Harris to decide to go to India to get a sex change? Because there is no reliable way to prove Sam Harris has a dick over the Web, I consider myself agnostic, as with the other questions.
