Radioactivity: Etymology/History and Physics [CC]

Marie Curie named Polonium "radio-active" in 1898, but why and why did anyone listen to a shy Polish immigrant who was also (shock) a woman? I use primary sources to describe why she discovered so much and why she was so influential. Ready? Let's go!

    I'm almost two years late, so maybe you've since learned these things, but I've got some pronunciation advice. German: >In German is pronounced like an English long E, as in "cookie" or "chief," but never as in "die." >German is often pronounced as /z/ (a thing English does too). A single before a vowel (so not at the end of the word or before a consonant) is read as /z/ >The easy way to remember both of these is by thinking of a German name you probably didn't know you know: Diesel As an aside, the "long I" sound is written as in German, think like "Einstein" ("INE-shtine"). EI = "I" while IE = "E." It's kind of the opposite of English; when it comes to words with we read "see," and lots of words use for "long I" (die, lie, cries, flies, ties, etc), although we do have words like "chief, achieve, grief" too. French: > I actually know a lot less about French pronunciation, but one thing I do know is that you never pronounce an at the beginning of a word. Think like the English words: honor, herb (unless you're British), honest, hour. All of these come from French and thus do the same thing of dropping the /h/ at the beginning. > Thus, "Henri" should be pronounced more like "enri," except I also happen to know this name, having heard it many times, and know that the is not like an English E, but rather more like "uh." "Henri" is more like "unRI." >Obviously, I wouldn't expect you to do the French R-sound correctly. The same goes for German. English R is good enough. I hope this info will help you not fumble new names as they come up in your videos. If you understand how these languages use the alphabet differently, you don't have look them up or make silly guesses based on your own English understanding of the Alphabet.

    So Marie was the first woman to win a Physics Nobel, and this year we had only the 4th, with Andrea Ghez for her work on the super-massive black hole in the centre of or galaxy. I have been meaning to get hold of a copy of Curie's thesis. I have read the story many times as it has been retold, but I had never noticed the Gamma Ray bit. That really needs to be more widely known. Another excellent video.

    2 or 3 things about Marie Curie: She worked doggedly for about 10-12 years in very sub-optimum conditions to get to her final conclusions and discoveries about radium and thorium and radioactivity in general. From my brief readings, she had to wear her wedding dress (and indeed, almost all the clothes she owned) to stay warm in her lab. The last thing I'll say is that the writeups of her conclusions seem so much more logical and concise than most of the other "discoverers" of the era. She was a very clear thinker/theoretician.

    Interesting, but doesn't get at the root of the etymology (which, BTW, has nothing to do with radix in the sense of "root") of "radio". The way I explained it to my students is to think of the radius of a sphere. A sphere has radii extending from the center in all directions. This is the characteristic of radiation: emission from a point in all directions. We refer to radiation in other contexts, too, as when the pain of a heart attack radiates from there into the arm, for instance.

    You are surrounded by all kinds of radiation, from radio waves (radio TV, phones) to infra-red (heat) to visible and even some ultra-violet from the Sun. Then there is some alpha, beta and gamma radiation from the air, the ground, and even our own bodies - about 8000 Bq from the C14 and the K40 in our bodies. There is also cosmic radiation from the galaxy. Lastly, if you have a medical examination there are x-rays and sometimes even gamma radiation (Tc99m) and those unfortunates receiving radiotherapy could have proton radiation as well as very strong gamma radiation almost to lethal doses but in stages, not all at once. No reason to be nervous, it is a natural part of life.

    Given that you put "etymology" in the title, it was disappointing to me that you didn't actually talk about the etymology that much. Thus I want to give more detail here: "radi," as in "radio," "radiation," all come from Latin "radius." You probably have an idea of what "radius" means from mathematics, the "radius" of a circle right? "Radial" means going out from a center, like radii of a circle, like rays of the sun...hmm... like spokes of a wheel... Sure enough, a "radius" is originally not an abstract mathematical word, but an ordinary one. It meant the spoke of a wheel. From that meaning, it came to metaphorically mean a ray of light, bursting out from the axle of the sun. "Ray..." hmm, that word again; there's something interesting about it, isn't there? It kinds of sounds like "radi" doesn't it? Aha!!! "Ray" is the French descendent of the Latin word "radius." "Rays" are things shooting out from a central source, like light from the sun, like spokes from an axle. "Radiation" is just a more Latinate way of saying "rays." That is the etymology! That's the reason "radio/ radiation" was chosen to describe these different "ray" phenomenon.
