    Time Travel

    I think I would time travel and fix up some things in my past. Then maybe we could all achieve perfection, if that is humanly possible since we are born making mistakes.
  2. I like the comparison between Alice and wonderland and Quantum physics!!!!
  3. Electricity and music both are connected not only through electric instruments but through our brain. In the second video it compares the brain to an orchestra and shows how even sitting down relaxed your brain is constantly moving. I also have had EEGs in order to monitor how my brain works during a seizure. Once I got to see a picture of my brain and all the electric currents going to all sorts of areas of my brain. The seizure would start in two different places in my brain then continue seemingly randomly until it ends. We don't exactly know what causes my seizures but one problem my family has is that our brains always move to fast for us to do anything with a lot of the ideas we have. The first video on the other hand reminds me of my brother and how he was electrocuted at a young age. I wonder if we had any detectors connected to him how fast the frequencies would be going then. I think my favorite part of the video was when you could hear the sound because it added a whole different dimension to how your body can help transfer different frequencies. With all the sound you could hear from his detector it makes you wonder what happens when you are using your cell phone. What frequencies go through your body? Can this really cause cancer? These questions and so much more are constantly being asked like how does are neurons know how to organize themselves in the brain when no one instructs them where to go. The brain is one thing I can't wait for the scientists to understand better so we can understand the miracles that happen inside us everyday.
  4. I wonder how long it takes us to receive the information gathered from the Kepler since we still haven't gathered the data from it's last years pictures.
  5. How did the German Scientists find out about negative Kelvin temperatures?

    Kinematics in regents is fairly easy and definitely helps with car crashes and measuring the different heights of things when you drop an object. equations like d= initial velocity times time + (1/2)(acceleration)(time^2) help when you drop an object with an initial velocity of zero on the earth and want to know how far it dropped assuming it landed and didn't blow up or explode or anything like that. For example if you explored some exotic planet with plants the size of skyscrapers and you wanted to find out how tall exactly it was if you measured how long it took for one of it's petals to fall, say it was 30 seconds and the planet had a known acceleration of 1.2 meters per second you could find out how tall it was by plugging in the numbers to the equation which would be 540 meters about the size of one of the World Trade Centers. If instead you drop a 25 gram weight off of the world's tallest building, which is Burj Khalifa in the United Arab Emirates a country next to Saudi Arabia, you would know the distance of 829.8 meters, acceleration of 9,81 meters per second and the initial velocity would be 0. if you wanted to find the final velocity you would use (final velocity62)= (initial velocity)+ 2(acceleration)(distance). This would end up with the square root of about 16, 280 about 127 meters per second. Yet if we really did drop a 25 gram weight off a skyscraper would it really kill you? As the weight falls the faster it got the greater air resistance it would experience. Eventually the air resistance would equal out with the gravitational force ending the acceleration which means only in a vacuum would it reach the speed 127 meters per second. That is also how skydivers can jump off air planes and not die because of parachute increasing the air resistance. These two videos are something I discovered while researching kinetics on You Tube. It talks about a different kinetics called rotational kinetics and though it goes into fuller depth explaining it with more videos, it connects a lot of the concepts we learned in regents physics to more places where we can use kinetics. In the second video it starts out talking about how rotational kinetics can relate to linear kinetics and talks about centripetal acceleration which we learned as v62/R and how it relates to bridge equations. Bridge equations relate what you've learned in pre-calculus to the regents kinetics you've learned in Physics and builds a bridge between math and science. I found this fascinating because I could understand the basic ideas of something I haven't yet learned by using the previous knowledge I have and making connections.
  7. I thought that the sense of gravity changing for the boxer that was punched was fascinating I didn't know it gravity played an important role in boxing except for falling.
  8. How much does the angle where the pivot is make a difference in how the drinking bird works?
  9. Imagine your standing on the edge of a plane ready to jump off. As you look out before you you get a little queasy and wondered if this really was a good idea. In order to stay safe you'll need a parachute but why do you need a parachute? First you start out with equal force between your normal and your gravitational force equal as you sit on the edge of the plane. Then the moment you move your foot in order to jump out of the plane the gravitational force pulls you back towards the ground. After a while the air resistance will reach the same force as the gravitational force is at. This causes you to stop accelerating downward but if it stops with a velocity of about 2000 meters per second you are still falling at a constant pace and you don't want to hit the ground with a velocity about 125 miles per hour. At this point you would pull the string to release your parachute this increases the air resistance and slows your speed down to a speed that you would live at if you hit the ground at it. The parachute adds to the air resistance because of its surface area and material it is made of. For an ideal parachute you would want one with a large amount of surface area, so the wind can get caught up underneath it and increase friction, and you would want it made out of the lightest material possible, so it doesn't add a significant amount to the gravitational force pulling you downward. If you had a heavy fabric as a parachute you would then increase both the air resistance slowing you down and the gravitational force pulling you faster towards the ground. If you were to make your own parachute more precise details would have to be considered like the shape and balance of the canopy so you could increase the amount of air molecules that get trapped under it and the friction it will cause. You also might want to consider a more round shape because it is far easier to balance a round shape than that of a triangle. Canopy vents would be another consideration so you can limit how the air molecules will escape the parachute and this would also effect your balance. keeping you in the air longer and at a slower velocity downward so you can be safe when you reach the ground.
  10. I love the references to Mr. Fullerton's hair and the cat in the box theoretical experiment along with the other pictures, especially the cartoons! I still don't completely understand Quantum Physics but it is fun to just enjoy the mystery. It makes you wonder what else is in the world that because of the way we are created we can't understand by our own nature of how we understand facts that are presented to us.
  11. I still cry at that scene too and I'm not surprised that Disney exaggerated. But it's interesting how even at the hight Mufasa was on the cliff he would've still died so it's not completely inaccurate.
  12. First let me warn you that I'm barely scratching at the surface of consciousness and the scientists still have a lot to learn. When you search this there seems to be two theories one that consciousness is similar to computers the other that consciousness revolves around the unity of different worlds and the reality as we see it is only an illusion. If you want to see a short clip of the physics of consciousness you can watch this: This only tells part of they story and other you tube videos can go on for a couple hours trying to explain consciousness. But one of the main points it brings up is that there is more in this world than by our human senses we can detect. Our bodies are made up of several worlds the one we see and can comprehend, the world of our cells and even smaller the world of the atoms that make up us. The world is made up of waves and somehow the world of intentions can change what goes on. One of the experiments that proved how your thoughts can change the way something turns out is an experimental machine that randomly generates coins of either 1's or 0's. They would tell people to try to count more ones than zeros and according to their results the number they thought about whether it was more ones than zeros or whatever would relate to the number of coins that the coin generator would produce. Another thing they talked about was how their is more than enough energy in the vacuum of space to produce universes. Yet we can't see anything but the vacuum can't be empty because of the continuation of stars being created out of seemingly nothing and the possibility that electrons can be both here and there and nowhere at the same time. Like Mr. Fullerton's cat in the box experimental theory he got from some other scientist trying to explain Quantum Physics. You would theoretically put a cat in the box with a capsule of cyanide that has a 50 percent chance of going off and killing the cat. Yet you couldn't see the cat or shake the box or the capsule would automatically go off. So you would assume the cat was both dead and alive like how with the double slot experiment with electrons you would assume it bounced of the background, went through both slits and also interfered with itself creating the interference pattern. So with the little I know and the information I learned from the video you can learn some interesting facts and concepts about consciousness that you might never have thought about before.

    Double Rainbow!

    Awesome not only are the rainbows beautiful but it's also fascinating when you talk of the physics.
  14. I never thought of looking into what the bees can see instead of the colors that we caal visible light. That and the picture really give you a sense of what a bees everyday must be like, as far as what they see.

    Infrared Waves

    Have you ever wondered what other animals see when they can see more electromagnetic waves than we can see? Well I started with this question and found that a common electromagnetic wave that other animals can see is infrared waves. There are three different types of Infrared waves, near, mid and far. In the following You Tube video Imre describes how you can take pictures of near Infrared waves using your camera. Even though it wasn't exactly what I was looking for the pictures give you an idea of what an animal might see and since my brothers are both photographers it reminded me of them. One of the facts that I found fascinating about Infrared Waves was that the far Infrared waves actually represent thermal waves which represent heat. Thermal Heat can be felt as heat from the sun and also can be found in fast food restaurants. Far infrared waves are closest to microwave waves which can explain why they can be felt as heat. Snakes would then use far infrared waves to see since they detect what is around them by the heat sensing organs in their face. Vampire bats can also use infrared waves to sense their warm blooded prey. Bugs use their antennas to detect infrared rays one reason is to detect prey. Beetles on the other hand detect infrared waves in order to find forest fires. After finding a forest fire they lay their eggs in the burnt wood. A different example is why NASA uses infrared waves to take pictures of objects in space. They take pictures of Earth in Infrared to help people study the clouds. For example they can see different layers of clouds with different temperatures. On NASA's website you can see a picture of Earth with darker warmer colored clouds closer to the Ocean and whiter clouds inland and close to the arctic. The colors you see with visible light also are made up infrared light as well. In one of their pictures you see a tree and waves reflecting off the grass one wave is visible light, which is why we can see that the grass is green, and the other is infrared light. When you take a picture of the grass and the trees with an infrared camera or camera lens, you see that the grass is mainly red which means it is either reflecting or giving off the infrared waves hitting it. This would explain why in the video they get better pictures when it's a bright sunny day because with more of the sun's rays exposed to the Earth there is a better chance that the Infrared waves will hit the plants, and reflect off different surfaces. Also some of the infrared waves will make the objects hotter that it is reflecting against also helping the camera to detect the infrared waves.
