1. The Secret of Life Reflection
Something that struck me in this video is that we are pressured to do what everybody else wants us to do in life. There is never a moment when we think just for ourselves, we always have other people's opinions and needs. Someone is always telling us that we need to succeed, when what we need to be doing is enjoying life. Like in the video, plants don't have someone or something telling it to live or succeed, they just let their life flow and guide itself, like the tao. I think that we need to live more freely and let what happens happen. The significance of this video is that we need to enjoy life and live it the way we want, without restrictions or letting other people get in our way because it all goes by too fast and before we know it, its gone.
2. Existence Reflection
I feel the significance of this video is that we can't have one thing without the other. For example, Alan Watts said, "...without eyes there is no light, without soft there is no rough, and without muscle there is no heavy." This makes me think of balance and that some things can't live without something else, they both give so that they both can grow and flourish. So if one thing can't exist without the other, what can't exist without us? Is there something other than nature and technology, that is somewhere else that can't live without us that we don't know about?
3. The Key to Science Reflection
What is different about science as a system of thought compared to other systems we have studied is that science is based on fact, logic and tests, while as the other systems are based on stories passed down from generations and experiences that only one person can justify. Science is about proving theories and asking questions, it is the only system of thought that we have learned about that we can actually prove what happened, we can't prove things from biblical times, we can only guess, assume, and trust what is written.
4. How People Disappear Reflection
What I found significant about this video is that we are quite ignorant to the people around us. Like in the video, people around us go missing and are practically forgotten about. Why is that we can so easily forget about people? This makes me wonder how many people disappear everyday and why. I understand some of the disappearances are because of death but, why do other people vanish? Sometime we can't understand what others are going through and how easy it is to hide everything with "I'm fine" and a smile. Even if you're close to someone you will never know everything in their life and maybe the things they don't tell you are the things that make them want to disappear.
5. The Physics of Skating on Ice Reflection
Something that I learned from this video is that when you start a spin in figure skating you use angular momentum, which makes you go faster, then you have a big moment of inertia to a small moment of inertia. The change from big to small make you rotate faster and helps you get more revolutions. Another thing that I learned is that there are different ways to sharpen a skate for different types of grip. The less grip you have the faster you skate and the more grip you have the slower you skate. Less grip is what speed skaters have because they have to go fast but, it makes it easier for them to fall. More grip is what hockey players have because they have to change directions very quickly. For figure skaters it is in between because they need grip and speed for their jumps and spins. Also I learned about friction melting, friction melting is when the ice at a skating rink, for example, melts due to the pressure of the skaters. The pressure makes it melt slowly though and that is why we are able to skate, the small amount of melting makes us able to glide and that is why the ice is easier to skate on after it is resurfaced. I feel like part of this video would be good to share with the class because it shows an equation for inertia and then it could be explained more in class, this would just add a more interesting aspect to learning about Newton's Laws.
6. Raptor Strikes Reflection
What I learned from this video is that raptors can make more precise moves and can see a higher flicker fusion rate than humans. I found this video interesting because before this I didn't even know that people did falconry. The precision that the hawks and falcons have is amazing, they can have their talons out in 47 seconds. I would love to research more about falconry and find out what they actually do. This video was different than the others from smarter everyday because it was a very unusual topic that not many people know about.
7. Rotational Inertia Reflection
Something that I learned from this video is that when you have smaller inertia you have more speed. In the video they show two weights with three weights closer to the center on one and three farther from the center on the other. The one with the smaller inertia went faster because the closer the weight is to the center the less inertia or resistance there is to spin. It is better to have less resistance. The change between the big and the small makes the rotation even faster.
8. Making Solid Nitrogen Reflection
In this video they show that when you take the air out of a container and boil the water inside, the temperature drops instead of rises. The first time they used water but, the second time they used liquid nitrogen. When they took the air out it again started to drop in temperature which make nitrogen from into a ice like substance. After they were done taking the air out they took it out of the container, they put in water and it made fog the same way dry ice does. In the end, there was a small disk of solid nitrogen that created fog and was floating across the surface of the water. I thought this was a really cool video because I didn't know that when you take the air out a glass tube, that the contents would boil.
9. Ice Cutting Experiment Reflection
Some thing that I learned from this video is that when you put copper wire on ice with two weights pulling it down, it cuts through the ice but, refreezes once it cuts through. This happens because when the pressure is applied it melts but, when it freezes the ice creates heat which helps the copper wire cut through the ice because the copper wire is a better thermal conductor compared to the fishing line they also used. The heat from the freezing ice travels, if quick enough, to make it easier for the copper wire to cut through. this process is called regelation. The same phenomenon is used when making a snow ball, when you put pressure on it it melts and when you release the pressure it refreezes.
10. How Laser Tattoo Removal Works
Something that I learned from this video is that when you are getting a tattoo removed the laser doesn't tae off the tattoo the first time, it takes multiple times. It takes multiple times to get the tattoo off because the laser breaks down the pigment beneath the skin but the white blood cells still have to take the pigment away and that takes time. By having the process done correctly, the tattoo will start to fade until it is gone. I think this is important because it shows how we have found ways to remove things and work on people from the outside, without having to do surgery or other methods and how far our technology and equipment has come over time.
Something that struck me in this video is that we are pressured to do what everybody else wants us to do in life. There is never a moment when we think just for ourselves, we always have other people's opinions and needs. Someone is always telling us that we need to succeed, when what we need to be doing is enjoying life. Like in the video, plants don't have someone or something telling it to live or succeed, they just let their life flow and guide itself, like the tao.
