  1. What is Onix Made Of?

    That's a whole lotta math! Well, you know what they say... gotta catch em all. Or in this case, Gotta catch all of em, meaning all of this ginormous baby powder beast into a tiny pokeball.
  2. A Sonic Boom of Light

    Oh no.. I posted about the same thing and only now just realized. Oops again!
  3. Hubble Space Telescope

    It would be so cool to work here one day.
  4. Why I spent $250 on a Swim Suit for Sectionals 2017

    Hm... Still sounds like a waste of money to me! Just joking
  5. Fall Damage

    Interesting! I might start working on my squat landings to prepare for any unexpected fall in the future. Also, this sucks when playing video games and you slip and end up falling to your doom.
  6. Stranger Things

    Uh oh, I didn't see this before I posted my blog about it either I swear. Sorry for copying you
  7. How Micheal Jordan Jumps so high

    My goals and dreams are to be as tall and jump as high as this legend. Cool post!
  8. Blog Post Checkpoint

    Procrastination is a wonderful thing got the best of me too.
  9. Physics in English

    As a part of your English class, I can say I was really humored by the conversation that took up a solid 10-15 minutes of class.
  10. Did you know that if you run really fast, you gain weight? Don't freak out, it's not permanent nor a noticeable amount. But say you ran as fast as the speed of light, the speed limit of the universe, and someone gave you a push. You wouldn't be able to go any faster, but you gain extra energy, and it's got to go somewhere. Where else but mass? Due to relativity, mass and energy are equivalent. This is highlighted by the universal equation of E=mc2. The more energy you put in, the greater the mass becomes. Unfortunately, this is basically negligible at human speeds, so Usain Bolt isn't noticeable heavier when running than when still. However, once you reach a decent chunk as a fraction of the speed of light, your mass will start to increase rapidly. Thanks, Einstein! I'm not sure if you will get this meme but it's sonic the hedgehog, notorious for being fast, clearly enthralled by this knowledge. I found it pretty amusing. And thank you, for tuning in.
  11. Stranger Things Fun

    Edit: I hadn't realized that Kara posted about the exact same thing until after I posted this, oops The popular mystery/horror TV show features a regular group of kids with a big discovery: parallel universes. More specifically it features the String Theory. This states that there are extra dimensions curled up into little balls. The teacher in the show does a good analogy to understand it: Picture our dimension as a tightrope, and we are an acrobat on this rope. The acrobat walking along the tightrope is huge compared to the thickness of the skinny rope! So, we see the rope as a one-dimensional line; we can only move back and forth along this surface. We never walk around the circular direction of the rope, because we'd fall off and we're too big for it. However, a flea walking on that same rope could not only walk back and forth, but also around the rope. The flea could also crawl down the side of the rope, and even underneath it. This suggests that tiny, miniscule particles would be able to travel in other dimensions! The more you know! Thanks for tuning in folks!
  12. Speed of Light Fun

    I read an article the other day that I thought was the coolest thing. It was about the speed of light and how it doesn't always travel very fast. In a vacuum, the speed of light is 300,000 km a second; however, light doesn't always travel in a vacuum. In water, for instance, light travels three quarters of that speed. The article goes on to mention what I thought was super interesting. In nuclear reactors, particles can be forced up to speeds so high they are often within a fraction of the speed of light. To add on, if they are travelling through a medium that slows light down, they could potentially travel faster that light around them. That's not even the cool part. When the particles travel faster than the speed of light, they emit a blue glow, known as "Cherenkov radiation." It's sort of comparable to a sonic boom but with light, which is why nuclear reactors glow in the dark. Here's an example of the Cherenkov Radiation. Additionally, the article goes on to mention that the slowest that light has ever been recorded moving was 17 m/s, or 38 mph. I can drive a car faster than that! And if that wasn't impressive enough, they top it off by saying that light has been brought to a complete stop. I don't know about you, but personally, that's mind boggling. Thanks for tuning in folks!
  13. Game of Thrones Fun

    As an avid fan of this show, it's really interesting to think about the physics that the creators had to make in order for this fictional realm to seem realistic. In fact, perhaps one of the most well known scientists, Neil deGrasse Tyson, has commented on both the good and the bad physics of the tv show. First of course, are the dragons' flight capabilities. “The dragon wingspans are sensibly large, as their body weight would require for flight,” he wrote. Also, note the fact that they don't have arms, as they have their wings as a replacement. Now lets talk about how they get off the ground. Based off some general consensus from aeronautical engineers, one dragon weighs about 2600 kg. Therefore, its weight is 26,000 Newtons. Each wing's area approximates out to roughly 32m2. Assuming the dragon takes off at its stalling speed, like airplanes do, that estimates to be 4.3 m/s, as its body length of 13 meters passes by in 3 seconds. Another thing is their flame spitting breath. Tyson comments that the blue fire breath would be at least 3 times hotter than the red fire breath, which is super cool and makes sense. Blue light requires more thermal energy to emit and therefore has a higher temperature. Its totally cool if you don't understand the context of this blog if you don't watch Game of Thrones, but dragons are cool too. Thanks for tuning in!
  14. Here's a little do-it-yourself physics experiment for anyone who cares: Ask your parents for a crystal wine glass. Be careful not to break it. Set it on a table and hold it firmly by its base. Now, get your finger wet by dipping it in water and slowly drag it across the top of the wine glass in a circular motion. If you have found the right frequency, you should hear a decently loud ringing sound. Why does this happen? Thanks to the delightful physics of resonance, we can understand this experiment. But first, here's a video of me performing the experiment. (I'm not sure if this works or not but I took a video on my phone and emailed it to myself to attach as a file so I don't know if it shows or not) IMG_1805.MOV When you rub your moistened finger along the edge of the glass, your finger sticks as it encounters friction. The water acts as a cushion to reduce the friction. When the friction is ideal so that your finger slips around the glass, vibrations occur on the sides of the glass. That vibration is then transmitted to the surrounding air creating a sound wave with a certain frequency, measured in per seconds (Hz). This is called a resonant frequency. A wine glass's resonant frequency is typically in the range of human hearing (20-20,000 Hz), allowing for us to hear the ringing. Thanks for tuning in folks!
  15. Polar Bear Fun

    What do you get when you cross a polar bear and a seal? A polar bear. (Cause it ate the seal) Just kidding. However, I do want to talk about these bears' fur. Did you know that Polar bears have clear fur, but black skin? But somehow their fur looks white. Here we ago again. A polar bear's coat consists of two layers of hair. A 5-15 cm long outer layer of guard hairs that are transparent, and a thick undercoat of shorter hair. Thanks to optics, these hairs appear white. Luminescence is the emission of light. When the sun's rays (Ultra Violet, or UV light) reflect off a polar bear's transparent fur, some light energy gets trapped causing the luminescence to occur. As the UV light shoots down to the base of the guard hair, the light makes contact with the bears skin, producing a whitish color. There's some useless trivia for y'all. Thanks for tuning in folks!
