  • Coffee: Magical Bean Water

    The World of Coffee

    With roots in Ethiopia and Yemen over 500 years ago, Coffee did not grow in popularity until America made it the drink of choice. This is closely linked to the history of our own country. After the tax from the Tea Act of 1773, America rejected Tea sold by the British East India Trading Company, and went to the cheaper alternative of Coffee. This brought it to the masses, and began its march towards global domination.

    Types of Coffee

    Pourovers

    The most popular form of coffee in the world is the pour over. It is a process where you pour hot water over coffee in a paper filter. This process is the basis of the drip coffee machine. It yields a fast to make cup of decent quality coffee.

    A famous coffeemaker that created the drip market is the Mr. Coffee. Have a listen:

    Percolated Coffee

    The older brother to the modern day drip coffee machine is the percolator. It has one major downside, of it resteaps the coffee multiple times, causing it to become bitter, it was very uncommon to drink this coffee black. Most people who drank percolated coffee have very little issue drinking black drip coffee though as it is far less bitter.

    Espresso

    Currently the king of caffeine, Espresso uses pressurized water to put the coffee grinds under pressure. You also have to grind the coffee finer to allow for the extraction process to work faster. This process requires some decently expensive equipment, and therefore is not a process normally done in homes, but budget espresso makers are becoming available. Starbucks made Espresso widely available in the United States.

    A guide for espresso:

    Moka Pot

    Before the modern high pressure espresso machine, there was still a way to make a higher pressure more caffeinated coffee than drip. It was called the Moka Pot. To use it, you would fill the bottom with water, a cup with coffee, and then screw it together. Placed upon a source of heat, it would force the water through the coffee under steam pressure. When finished, it would make a noise that sounds like the word Moka. This told you it was done.

    I am writing about diamonds in the left side column. Let’s pretend that I run a business that sells diamonds. Underneath this bit of text, I might put a button to go buy diamonds. I will offer you a diamond for 3 emeralds. Also equivocal to 13 loafs of bread. Hmmmmmm.

    I like rocks a lot…. is it obvious? Some rocks are pure elements, but others are an amalgamation of many different compounds made in many different ways.

  • Radium

    A highly radioactive Alkaline Earth Metal, Radium is mostly phased out of modern usage due to the hazards of working with it, and owning it. None the less, it is known for its radioluminescence capability.

    Quick Facts

    Atomic Number88
    Atomic Mass226
    Melting Point700 C
    Boiling Point1737 C
    Density5.5g/cm3
    Discovered ByMarie and Pierre Curie
    Year Discovered1898 (Isolated 1910)

    History of Radium

    Discovered by the Curie’s, Radium was originally looked at as a “Miracle” element that could help create long lasting glow in the dark materials that to this day brilliantly glow. It was also pressed into service as a cosmetic, toothpastes, and in radium water for vitality. Because it had so much extra energy, and because we didn’t understand the idea of radiation sickness yet, we used it everywhere. This was unfortunately not a great idea.

    In the 1920’s the girls who were painting the dials started developing severe damage to their faces as they would lick the tip of the brushes that they used to help straighten out the bristles. This led to damage to the bones and cancers.

    It was also used for cancer treatment though, a job it still sometimes is used for to this day. Alas, due to the tragic deaths of some people, radium was phased out of heavy usage and is now heavily restricted. With that said, if your grandparents have an old glow in the dark clock, and it glows very brightly, it might be wise to break out the Geiger-counter because you might have a rare Radium Clock.

    Where it’s used today

    Radium is a reliable radioactive source and so it is used for Radio-Clocks that use decay to tell time. It also sees usage as a industrial radiography machine that looks for flaws in metallic parts like an X-ray. It is often mixed with beryllium to act as a neutron source. It’s most common job though is to act as a material to enrich to create other synthetic elements.

    For the most part though, Radium is only used in very special cases and has been phased out and it is not actively mined since the 1970’s. Almost all Radium is now recycled from prior usage. It is also considered one of the most toxic of radioactive elements, even more dangerous to your health than Plutonium and Americium.

  • Radiation: Is it really dangerous?

    “Unless you are purposely collecting and storing radioactive materials very incorrectly, it’s not dangerous.”

    Since the 1940’s we have always looked at radiation as the monster that had to be conquered or feared, but is it really as bad as science fiction would have you believe? Let’s explore this concept.

    The Facts

    Many people believe that Radiation Illnesses are a major factor for dying of cancers, but the facts just don’t back this up.

    IllnessRate
    Skin Cancer60,000 – 90,000
    Smoking7,000,000 (1.5m from secondhand smoke)
    Acute Radiation Syndrome60-100 SINCE WWII
    Per Capita Mortality of different diseases

    The Truth

    Radiation is a calculatable risk. We use certain tools to keep a safe measurement of this risk, but in most cases, radioactive material that most people can gain access too is not very dangerous. We have lived alongside it for thousands of years, and unless you are purposely collecting it and storing it very incorrectly, it’s not dangerous.

  • The Metric System

    The Metric System has been adopted by most of the world, but in The United States of America it never really caught on. There are some major measurements that can be made in Metric. The primary sizes are as such:

    • meter – length
    • gram – mass
      • kilogram
    • Celsius- Temp
    • Candela – Luminosity
    • Liter – Volume

    A famous quote:

    If God wanted us to use the metric system, he would have given us ten fingers and ten toes.
