Originally discovered by accident, X-rays are now used about 100 million times a year in clinics around the world. How do these magic eyes work? Ge Wang details the history and mechanics of the X-ray machine and CT scanners.

Why are most important stuff made by accidents

@aminetanouyat9643 5 жыл бұрын

Because we are lucky lol

@buttonpusher3786 5 жыл бұрын

Because you can't predict the result of every experiment and what the result can be used for in the future. Also it was only discovered that way, it's not like the ct scanner was created by accident, it was designed using a huge number of known parts and principles that would provide a desired effect.

man, in those times, these weren't considered chores. I doubt you consider these chores. Right now everyone could be winning noble prizes, but we don't.. Why? because the experiments carried out byt scientists these days are not considered chores.. But in a few 100 years, they may seem simple. RIght now to us they are revolutionary, because our society is advancing scientifically because of these "future chores". Don't belittle those scientists' hard work please.

The lead aprons aren't enough. You'll need a thyroid guard as well. I just had my thyroid removed two months ago due to thyroid cancer.

@buttonpusher3786 5 жыл бұрын

shpongloidia There's plenty of evidence to suggest that aprons and other shielding on patients can cause more internal scatter and therefore a higher dose. For that reason a lot of paces don't offer them to patients. Comforters and carers and obviously medical staff won't have an area being imaged and therefore shielding can be used more effectively to prevent exposure. Also the thyroid shield would likely either be in the way of the image or so far out of the way as to be negated as it's such a low dose.

The cathode ray depicted is wrong. (He most likely used a "Lenard tube" which you covered but he also had other tubes but none of them had a cross in it with a hinge) Also, as he was creating x-rays from bombarding either aluminum or glass with beams of electrons he was not making "characteristic x-rays" (I think they put it as "rearranging the electrons in the atom and producing x-rays" as glass and aluminum and other low mass items tend to absorb that x-ray and produce another electron instead, called an Auger electron (if you type in Auger electron you can see a nice graph of it).

@buttonpusher3786 5 жыл бұрын

Kathy Loves Physics I think this is a point at which the video is unclear but bremsstrahlung and characteristic are the two ways they are created in modern plain film use. The video was not clear when moving from his experiments to modern use, likely as it was trying to interest those with limited knowledge of the process and didn't want to complicate what is already a difficult topic.
