      The best rock I collected was an inch in diameter sized obsidian. It was found on the beach where we use to swim at when we were younger. It's the best because there were no volcanoes nearby, so I think it was washed up ashore from somewhere really far, or there could be a fault line below the ocean floor. As a kid I was amazed that all of us are made from the same elements from the earth. I was always fascinated by how everything on earth seems in someway tailored so that life can thrive on it. I think humans beings in general are made to be curious, always asking questions why and how. Maybe the reason why we, when we were just little kids, ask a lot of questions. We're just made that way and I really think that this is one of the characteristics that separates as from other animals. The endless thirst for answers to things we don't understand.

      JK. I did learn about Raman scattering experiments in physics class. Interesting to learn about the man himself.
      I once heard another story about a scientist with a collection. The American chemist George Washington Carver, known for his many uses for peanuts, was visited by a wealthy tycoon, who offered to give him a gift to reward him for his gifts to humanity. He asked for a diamond, and the tycoon, thinking he could sell it to help fund the lab, shipped a large uncut diamond to Carver. On a later visit to Carver's lab, Carver showed him his element collection, in progress. Sure enough, the unprotected compartment labeled "CARBON" contained the diamond!
      I wish I could remember the name of the tycoon, a well known Gilded Age manufacturer.

    Professor, the first ever actual atom bomb was the one detonated in July 16, 1945, at the Trinity Test Site in New Mexico, US.
    Hiroshima bomb fell in August 6 of the same year, and was the first nuke to be used in warfare, the first Gun Type design nuclear bomb to be detonated (They were so sure it will work that didn't bothered to test it), the first nuclear bomb using Uranium to be built and detonated, but overall, the second nuke to be ever detonated.
    The trinity Bomb was of Implosion type, fueled by plutonium, and was identical to the bomb that fell in Nagasaki in August 9.
    The three bombs completion time is classified, but given the time between the Trinity test and the bombings, there's enough time to assume the two later bombs were built after the test.

    Asbestos is the common name for six naturally occuring fibrous silicate minerals.
    I work in demolition business in Finland and asbestos is something I'm very concerned about when demolishing old buildings (I wear professional respirator mask tho). In Finland it was banned in the 90's but it is still everywhere and I mean everywhere from wall glues to mortar paste to air conditioning pipes and especially around heat pipes.
    The blue/purple one "crocidolite" is the most dangerous and it will almost 100% lead to lung cancer if breathen even short period of times. It is 1000 times more dusting than the "safest" white asbestos "chrysotile" which is the most common in old houses.
    Asbestos is safe to touch and is harmless if not disturbed but if you break an object or handle already broken object containing asbestos it releases thousands and thousands of nano-sized needle like fibres in the air. When you breathe them in they get stuck to your lung tissue.
    Asbestos is really stable and non-toxic. It is chemically and mechanically resistant so when those nano-sized fibres get into your lungs they won't react with anything and won't dissolve but with every breath they stab deeper and deeper to the tissue. So the only thing your body can do against these tiny lung stabbing hypodermic needles is to contain them and produce more and more scar tissue around them until you have lung cancer "mesothelioma".
    With white asbestos the latency time is from 15 to 40 years before you might develop mesothelioma. With the blue one it is around 4 years and you will be in the coffin.
    WTC buildings contained around 400 tons of asbestos and when they collapsed majority of it was released in the air thus why lung cancer is the most common cancer and new cases are increasing every year in NYC among other respiratory diseases.
    Also the US government recently legalized again the usage of asbestos in construction materials not including cement.

    • @revenevan11
      @revenevan11 4 года назад +8

      Why did they legalize it again? It's a public health threat which many are scared of, and I hadn't even heard of the bill proposing to re-allow it. Is there any pushback against it, or anything people can do to stop it from being used again?

    I think I've been in that salt mine in Poland. A most magnificent place that would rival the mines of Moria or Erebor. Vast halls, with carvings everywhere. A number of churches, and an entire cathedral. One of the most beautiful places I've ever been, with an air so pure that it cleared the longs of asthmatics. Even the story of the mine would fit into Tolkiens works. I will not spoil the story for you, visit the mine, or look it up if you want to spoil yourself. I would love if you went there. Such beauty, carved out of rock and salt.

      I would slso have preferred that my country's education system treated the sciences as a kind of "history of the arts" style course that systematically takes you through the process of discovery from the discoverer's point of view instead of just glossing over the conclusion and assigning some seemingly disconnected labwork...

    For those interested in the mechanics of fluorescence, the UV light excites some of the electrons in the mineral, causing them to temporarily jump up to a higher orbit. Upon falling back, the extra energy is released as a photon, who's color depends upon the amount of energy it took to excite the electron in the first place, creating specific colors for different substances.

      I was under the impression that it was artificial rubies which fluoresced as they deliberately put a dye in them. I saw a Nat Geo documentary decades ago on gemstones which included the manufacturing process. The company director said that they’d been offered massive $$$ to leave the dye out. Also, I have a faceted artificial ruby which I bought at a gem show... It does fluoresce under UV. It comes up orange. Was fairly inexpensive, too (I’m an amateur gem collector and gold/silversmith).

      Funny thing. Crocidolite isn't the only "asbestos". Asbestos is just a description for minerals that crystalize into long fibers.
      Anyway chrysotile is the most common asbestos type used in the US and if you look at it under a microscope it actually looks a lot like his hair. The way my boss described it (I work in an asbestos lab) is that it looks thin and wispy like old lady's hair.

    [Apologies if someone has already brought this up.] Remember that all ruby laser rods are synthetic; they fluoresce very brightly, even more so than natural ones. I'm not sure what prevents the synthetic specimen in Raman's collection from fluorescing well, unless perhaps the doping level is excessive.
