Igloo

Igloo Building

Lucky for me, we bought my dad a snowblower for Christmas a couple of years ago. This allowed us to make a large pile of snow (using the snow from the driveway.) This pile of snow became the foundation for our igloo. We pretty much patted down the snow so that the pile was nice and sturdy, and then began digging a hole through the front of the pile. Once the hole was large enough for me to climb into, I started using my hands to pack the roof super tight so that it would not collapse into the shelter. Once this was done and there was a large hole through the front of the igloo, we added a couple of windows so that there would be enough oxygen getting into the structure. Snow makes up the roof, floor, and walls of the igloo. Although it is not seen in the picture, a storage container lid is placed in front of the door to block any wind that would try to come in. It is probably hard to tell since I am laying down inside the structure, but it is large enough for one person to fit in if they are sitting Indian style or if they are laying in the fetal position. Of course, if they wanted their legs to freeze they could also leave their legs sticking out of the structure as I did.

Making this igloo was a really fun way to enjoy the freezing weather that we are having. Hopefully, if I was ever stuck in the wilderness in this sort of weather, I would be able to make a structure like this to keep me protected from the elements. It was definitely helpful that my dad made this with me since he is a much better igloo builder than I am and it took a lot less time than it would hav eif I was building it by myself.

Physics of Black Holes...Or Lack Thereof

Isabella Jacavone To comprehend how the universe works, we must dwell into the most basic building blocks of existence; matter, energy, space, and time. NASA's Physics of the Cosmos program involves cosmology, astrophysics, and fundamental physics intended to answer questions about the elusiveness of complex concepts such as black holes, neutron stars, dark energy, and gravitational waves. In this blog post, I'd like to elaborate on a subject that is very intriguing to me; Black holes. And more specifically, what would happen if we got near one. A black hole is anything but a hole, but rather an immense amount of matter compacted into an extremely small area. A black hole is caused when, hypothetically, a star four times more massive than our sun collapses into a sphere no bigger than 600 square km. To put that in perspective, that's about the size of New York City. B lack holes were predicted by Einstein's theory of general relativity, which showed that when a...

Physics of Sound Dampeners and Active Noise Cancellation

Physics of Sound Dampeners and Active Noise Cancellation Sound dampening foam panels in a recording studio. ANC headphones worn by pilots and/or passengers in consumer aviation aircraft. Acoustic treatment of soundscapes has grown alongside the sound production industry. Whether through absorption panels, diffusors and cloud panels to treat a space or headphones placed directly over the ears of listeners, acoustic treatment comes in many forms. Environments are treated acoustically to absorb excess sound to prevent sound levels from crossing a threshold above which the desired goal cannot be had. Before getting into sound dampening, we must discuss sound. Sound is produced when an object vibrates (a form of oscillation) and temporarily displaces nearby air molecules causing a wave effect as the displaced molecules collide with their neighboring molecules. Sound waves are fluctuations in pressure as the initial displacement of molecules experiences collisions that in ...

Aerodynamics of a Golf Ball

One may wonder how a small golf ball can travel at incredibly high speeds for such long distances. While the swing of the club is a major component, the structure of the golf ball is quite important. Unlike a baseball or tennis ball, a golf ball has dimples all over it (usually 336 dimples). These dimples allow the golf ball to travel without facing much air resistance. This diagram shows how air travels around the golf ball. The dimples on the golf ball also prevent drag that would occur in the wake region, resulting in further distance. Also due to the contact with the club during the swing, the golf ball has backspin during its entire flight. This diagram shows the motion of the golf ball mid flight with the lift force of F. There are hundreds of different types of golf balls that a player can choose. Some show little affect to a player's game while others can alter their performance completely. Personally, I prefer Callaway Supers...
