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!

Gotta go feast

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.

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!

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.

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.

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. Game of Thrones

“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.DKhTdJqX0AAmje-.jpg

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!

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)

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.

What do you get when you cross a polar bear and a seal?

A polar bear. Image result for polar bear laughing(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.

This classic viral video sparked a nationwide disturbance of young kids annoyingly flipping water bottles to no end. At the same time, we've all tried it. But those kids are still annoying.

Anyways, ever wonder how the water bottle is actually able to land perfectly on its bottom after being spun? Me neither! Until the other day when I was brainstorming ideas for blog posts. So I'll tell ya. 

First of all, you need the ideal amount of water inside your bottle. The most preferred type is a 16.9 oz classic. Fill that bad boy to as close as 1/3 of the bottle as your eyes can measure.

Holding the bottle by the top, the water and center of gravity rest in the base. On a perfect throw, the ideal amount angular momentum causes the bottle to rotate. While it is rotating, the water doesn't stay at the base. It sloshes around, shifting the center of mass towards the center. The light bottle allows for the angular momentum to transfer with the heavier water, resulting in a decline in spin speed. At this point the bottle is basically upright and gravity does its thang the rest of the way to the table.

I know you were dying to hear about the physics of the most aggravating fad of 2016. You're welcome. Thanks for tuning in folks!

Anyone who has ever held a basketball has tossed it up, spun it, and let it bounce on the ground. Don't deny it. You'd watch it bounce back up to you just like you should have. But did you notice how it was spinning? Perhaps you spun it towards yourself, and without noticing after it bounced, I can guarantee it came back up spinning away from you. What sorcery is this? I know you are dying to know, so I'll tell ya. 

Optical Illusions are fun!                    animated-basketball-image-0074(which way is it spinning?)

First things first, this doesn't only happen with basketballs, but the basketball is a good example. 

A basketball is elastic. This means that when it hits the floor, the part of the ball in contact with the floor stops moving momentarily, yet the rest of the ball is still spinning. Consequently, this creates tensions between the two sides of the ball, slowing the rotation down, and storing some elastic energy. When the entire ball stops spinning, this energy will reach its maximum, releasing in the opposite direction while the basketball will leave the ground. And finally, this causes the ball to rotate in the other direction. I think it's crazy that all this can happen in one instant! 

Well there ya have it. Your curiosity is cured. You are welcome!

Thanks for tuning in, folks!:money:

Video 1: 

A) “Beliefs That Make You Stupid”:

-Learning is fast

-Knowledge is composed of isolated facts

-Being good at a subject is a born talent

-I’m really good at multi-tasking

 

The belief that “learning is fast” relates to me because procrastination is clearly a big struggle with me, which shortens the time I give myself to learn something new immensely.

 

C) Metacognition is a student’s awareness of their level of understanding of a topic.

 

Video 2: 

A) The most important factor in successful learning is “what you think about while studying”. It’s important to deeply process material rather than skimming the information.

 

B)”Deep processing” means being able to relate this new information to prior knowledge and making it personal

 

C) Items That Help Learning:

-Minimizing distractions; maximizing focus: I can make sure that I am in a quiet study area without my phone.

-Developing accurate metacognition: I should ask for help instead of settling for a basic understanding.

-Deep, appropriate processing of critical concepts: I need  to make sure I understand something before moving on.

-Practicing retrieval and application: I should use the information I learn to help with homework.

 

Video 3: 

A) Aspects of Optimizing Learning:

1. Elaboration: the ability to relate concepts.

2. Distinctiveness: the ability to separate the concepts.

3. Personal:the ability to relate to experiences.

4. Appropriate to Retrieval and Application: the ability to recall the information.

5. Automaticity: a process so highly practiced that it occurs without any conscious effort.

6. Overlearning: continue studying beyond just knowing information to where it can be recalled easily

 

Video 4: 

A)

  1. What’s the best way to minimize distractions?

  2. How do I develop Automaticity?

  3. Why would it be worse to take notes on a laptop rather than by hand?

  4. What are the four beliefs that make you stupid?

  5. Provide an example of a time where you overlearned a subject and it benefitted you.

 

-”Provides a key summary”: writing down the main terms that will be called upon later

-”Creates a set of memory cues”: help remind you of what you missed

-”Engages you in the class”: determines whether or not you processed the information deeply or superficially

 

C) I will get a study group formed with my classmates with goals like these:

  1. Create a calendar and schedule

  2. Set daily tasks

  3. Split up work so that everyone can ask/ answer questions

 

Video 5: 

A) If an exam goes poorly, I shouldn’t panic or go into denial.

 

B) Helpful Strategies to Raise One’s Grade include identifying how you prepared for the test and acknowledging your mistakes, going over the exam to see what you did wrong, analyzing your weak areas, checking key concepts missed in your notes, and improving your study strategies.

 

C)Commit your time and effort, go to class, do all the homework, don’t slide and let the homework for one class prioritize over another.

I am thee.

    I like cookies and chicken. Two Cs. Just like AP Physics C. I also enjoy playing guitar in my free time and long walks on the beach. I am also an avid fan of the series Game of Thrones. As a varsity setter on the volleyball team, I have to take in each unique play and react based on the situations on the court. This relates to physics in which every problem is a new situation and I like a challenge. I hope to get a real sense of what careers in this field I may be interested in. I'm most excited about teaching ourselves. Not because it sounds like a blast, but because I can use the skills I develop to help me succeed in college. However, I'm super anxious about the tests and workload because I know how difficult they can get. Thanks for tuning in on my first blogventure. Catch ya next time.
