Why Nuclear Energy Is Great

When you hear the words “nuclear energy”, you don’t usually think of clean, efficient energy, but rather dangerous and hazardous to the environment. Nuclear energy is very misunderstood by the general public or people who have not done some research on it themselves. Nuclear energy is actually one of the most environmentally friendly sources of energy, it isn’t as clean as wind or solar energy though, but it is significantly more efficient. The production of nuclear energy doesn’t emit any greenhouse gasses, which is the main culprit for global warming. Greenhouse gasses absorb certain frequencies of infrared eradication and scatter them back to the surface of the earth, heating it. Greenhouse gasses prevent heat from escaping the earth, keeping it warm, which can lead to the melting of the ice caps, which will lead to dangerously high sea levels. A nuclear power plant actually emits fewer radioactive materials into the environment that a traditional coal burning facility. It is estimated that nuclear energy has saved 1.84 million lives by not releasing countless pollutants. Nuclear power is more efficient than other sources of power. It is estimated that nuclear energy has a 91% efficiency rate. Actually building a nuclear power plant will cost a lot more than a power station that generates the other types of energy, but nuclear energy itself is cheap. In 2007 the cost of nuclear generated electricity was 1.7 cents per kilowatt hour, the cost for coal for 2.4 cents, 6.7 cents for natural gas, and 10.2 cents for oil. Nuclear energy has an enormous capacity. One kg of 4% enriched fuel grade uranium released the same energy as almost 100 tons of coal or 60 tons of oil. Each year the US saves $12 billion dollars on energy costs because of nuclear power. Nuclear power plants save a lot of money that could be used on great things such as hospitals, education, and making sure people are fed. One in five households and businesses receive power from nuclear power plants in the US. 13% of the worlds energy comes from nuclear power plants, even though there are only 449 of them in 30 countries, as of April 2017 there are 60 new nuclear power plants under construction in 15 countries. Nuclear power is extremely powerful so there must be some serious downsides when handled incorrectly. What about the safety of nuclear energy? Nuclear energy is used in massive bombs used to blow up entire cities so it must be super dangerous right? Accidents in nuclear power plants are far more harmful than accidents in other power stations but the risk of an accident is low and declining. A repetition of the famous 1986 Chernobyl disaster, which displaced over 300,000 people, is virtually impossible. Hopefully after taking in all this information you are now informed on why nuclear power is not the terrible thing you may or may not have thought it was. I believe that nuclear power will be the main energy source in the future because of how great it is.

The Magic of Light

The video below looks just like magic, how can something just change by itself right in front of our eyes? Well, with some understanding of waves we can explain this phenomenon. The big idea, or sole reason to this so called magic is refraction. When you look at the glass the light rays bend around the center of the glass, causing the light rays to intercept each other between the glass and the arrow, or piece of paper, creating a focal point, the light that was on the right side is now on the left and vice versa, this causes the arrow to appear to be inverted, which makes it appear to be backwards. Anytime light light goes through one medium into another, it refracts. In conclusion this is in fact not magic, but can be straight forwardly explained using wave physics.

Waves

This clip is demonstrating destructive interference, one person flung the slinky down and the other flung the slinky upward, when the waves meet in the middle they cancel eachother out making the slinky take the form of a flat line once again.

This clip demonstrated constructive interference. Both group members flung the slinky in the same direction (up or down) at the same time so that the waves would collide, when the waves collides they constructed a bigger wave, like they combine forces.

In our third trial we rapidly slinged the slinky back and forth, our goal was to find how many node points we would make with our slinky, a node point is basically one wave, if it takes 3 waves to reach the other end the slinky has 3 node points. It is a lot easier to see if the slinky is going at super rapid speeds but we counted 3 node points on our slinky.

Physics 11 – Archimedes Challenge

27 November 2017

For the “Archimedes Challenge” we had to build an ancient machine, the machine me and my group constructed over a course of 4 days is called a trebuchet. The trebuchet was invented in China in 300 BC. It is unknown who exactly invented the trebuchet but the machine was used by the Mohists as early as the 4th century BC, Mohism was an influential philosophical, social, and religious movement in ancient China. The trebuchet was invented for the purpose of war but more specifically sieging. Sieging is when military forces surround a town or city with the purpose of cutting off supplies, forcing a surrender. The trebuchet was not invented simultaneously in different places but eventually made its way to the west due to the Avars. The Pannonian Avars were a group of Eurasian nomads of unknown origin during the early Middle Ages. The short term effect was that whoever had access to the trebuchet had a great advantage when sieging because nobody would have prepared for such a weapon yet. Long term effect is that cities were forced strategized against the trebuchet like maybe building walls differently which could lead to some new discoveries in engineering.

The trebuchet we made in class is a little different than a traditional ancient trebuchet. Instead of a rotating axis for the throwing are to slide on, we used a hinge instead to attach the arm to the beam and still give it a very large throwing radius. We have elastic bands attached to one side of the throwing arm, on the opposite side of the payload basket. When the side of the payload basket is pulled down, more and more potential energy builds up the farther you pull it down. When you let go, all that potential energy turns into kinetic energy and the throwing arm throws whatever object with great force.

Day 1:

We spend the class discussing as a group what we would like to build, we settle on a catapult and plan to fully design our catapult the next day.

Day 2:

We have a bit of a debate wether or not we should make a catapult because we notice a lot of other groups have the same idea as us. We make our idea more unique by making a trebuchet, which is sort of a catapult but really isn’t and our idea will be totally original. We make a very rough sketch of what our trebuchet will look like.

Day 3:

We secure 4 pieces of wood into a frame very strongly together using a hot glue gun, it is crucial we get this part perfectly or our trebuchet will not be strong enough to handle the recoil of the force it is putting out.

Day 4:

We use nails to make the rest of the body, we then attach the beam using a hot glue gun, we attach the throwing arm to the beam using a hinge and nails. we test the trebuchet out and the beam fails or straight up flies off so we decide to use nails to secure the beam instead, we test out the trebuchet several times and it is fully functional. The building process is now complete.

“Lord of the Flies” – island description

(a brief description of what the island in “Lord of the Flies”, may look like.)

1) Scar

“between the scar and the sea. There, too, jutting into the lagoon, was the platform, with insect-like figures moving near it.” (39)

2) Lagoon

“A great platform of pink granite thrust up uncompromisingly through forest and terrace and sand and lagoon to make a raised jetty four feet high.” (13)

3) Mountain

“his eyes and followed the jagged outline of the crags up toward the moun- tain. This part of the beach was nearer the mountain than any other that they had seen.” (33)

4) site were Ralph and Piggy find the conch

“Ralph had stopped smiling and was pointing into the lagoon. Some-
thing creamy lay among the ferny weeds.
“A stone.”
“No. A shell.” (18)

5) Forest Where Fire Happened

“The pile was so rotten, and now so tinder-dry, that whole limbs yielded passionately to the yellow flames that poured upwards and shook a great beard of flame twenty feet in the air. For yards round the fire the heat was like a blow, and the breeze was a river of sparks. Trunks crumbled to white dust.” (56)

6) The Conch Location

“The shore was fledged with palm trees. These stood or leaned or reclined against the light and their green feathers were a hundred feet up in the air.” (10)

7) fruit tree

He picked his way up the scar, passed the great rock where Ralph had climbed on the first morning, then turned off to his right among the trees. He walked with an accustomed tread through the acres of fruit trees, where the least energetic could find an easy if unsatisfying meal.

8) coral reef

”The reef enclosed more than one side of the island, lying perhaps a mile out and parallel to what they now thought of as their beach. The coral was scribbled in the sea as though a giant had bent down to reproduce the shape of the island in a flowing chalk line but tired before he had f inished. Inside was peacock water, rocks and weeds showing as in an aquarium; outside was the dark blue of the sea. The tide was running so that long streaks of foam tailed away from the reef and for a moment they felt that the boat was moving steadily astern (Golding 38).

9) Mountain

“Where the pink cliffs rose out of the ground there were often narrow tracks winding upwards. They could edge along them, deep in the plant world, their faces to the rock“(Golding 34).

10) Scar

”Jack pointed down. “That’s where we landed.” Beyond falls and cliffs there was a gash visible in the trees; there were the splintered trunks and then the drag, leaving only a fringe of palm between the scar and the sea“ (Golding 39).

11) Shape of the island

“It was roughly boat-shaped: humped near this end with behind them the jumbled descent to the shore.”

12) Jungle

“Trees, forced by the damp heat, found too little soil for full growth, fell early and decayed: creepers cra- dled them, and new saplings searched a way up.”

13) Ocean

“faced by the brute obtuseness of the ocean, the miles of
division, one was clamped down, one was helpless, one was condemned” (Golding 158).

14) is an island

“This an island. At least I think it’s an island. That’s a reef out in the sea” (Golding 7).

 

 

 

 

September Lab Reflections

September Lab Reflection

I chose to reflect of the sunflower crepe lab because it was the best tasting thing we

made this month. One thing that went well was the final product, it was more delicious than I

was expecting it to be. The only thing that went wrong was that we went a little bit over the

time provided because we were having some difficulties understanding the recipe. The thing

that confused the group was which ingredient do we take double of because we were making

the sunflower crepes in groups of 2 in our table of 4 definitely make this again because it is not

that hard to make and it tasted really good. I also chose to reflect on the croissant recipe I was

not present at school the day they were baked unfortunately. I heard they were delicious. What

went well was despite having a major setback we still were not that late for the next block. Our

mistake was we added where we were not supposed to and had to redo the entire recipe

which took around 15 minutes. Another setback was a custard cup made of glass slipped out

of my hand and shattered onto the floor. I had to leave my group to clean up my mess. I would

definitely give the croissants another shot just for the sake of doing it right and actually getting

to actually taste them which I could not originally do because I was absent.

 

 

 

“Secret Life of Walter Mitty” Narrative

“The Secret Life of Walter Mitty” Alternate Ending

 

As Walter faces the firing squad he has a mysterious smile on his face, almost as if he was insinuating his escape, the soldiers are confused and look back viciously, and are eager to shoot him. “Hey! Our guns don’t work!”

“they’ve been tampered with!” Said one of the soldiers.

Walter laughs, and pulls the grenade that he was hiding in his pants the entire time, Walter throws the grenade at the confused soldiers. The soldiers in distraught dive for cover and Walter escapes with a huge explosion behind him into the mysterious war torn city that he would have been executed in…

“Walter why did you throw your wallet into the middle of the parking lot?” Asked Walter’s wife.

“Oh my bad, it must have slipped out of my hands,’ said Walter.

“Whatever, we can go home now we’ve done everything we need to do” said Walter’s wife.

on the way back to the car Walter sees a store with some very nice watches. He notices one specific watch that completely stands out from all the others… Walter finds himself standing over a bomb big enough to blow up the entire building and the criminal he detained who planted the bomb near him.

“Tell me the code!” Yelled Walter, trying to sound as intimidating as possible.

“Why would I tell you anything! Either way i’m dead!”, said the insolent criminal.

Walter knew the criminal had a great point, so he knocked out the criminal with a pipe knowing that he would be no use to him if he wanted to defuse the bomb, he would only be false hope, a distraction. Walter had to figure it out himself. Walter with very little knowledge of bomb defusing aside from some action movies, started inspecting the bomb looking for anything that could help him. All he could find were three wires that were all the same color, “hmm, one and three chance? Those are the best odds I’ve had in years,” Walter cut one wire with little to no hesitation and the confidence of a mad man…

“you’ve been looking at that watch pretty intensely” said one of the watch store employees “if you are looking to buy it today there is a 15% discount,” said another employee.

“oh, ummm, no thanks, just looking around” said Walter.

“Are we finally done here?” Said Walter’s wife as he walked out of the watch store.

“oh course honey,” said Walter.

“whew thank god we’re going, nothing interesting has happened today, I need a nap,” said Walter’s wife in a whiny tone.

“of course,” said Walter as he was blankly staring at a very uninteresting puddle.

“Walter you’re making that funny look again, what is going on in your head today?”
