Electric House Project

Welcome to my Electric House Project, for this project, myself, Stephanie and Emily created 4 different rooms with different electrical circuits. They rooms we made were a Bedroom, Bathroom, a Kitchen, and a Living room.

 

1.You have 3 light bulbs. all have the same intensity when lit. explain how you can prove to a classmate that they are connected in series by unscrewing one light bulb. support your answer.

When/if all of the light bulbs are turned on, to prove that they are a series, you can unscrew the first bulb of the circuit and then if you wired it correctly, the rest of the lights should go out.

2.You have 3 light bulbs. all have the same intensity when lit. explain how you can prove to a classmate that they are connected in parallel by unscrewing one light bulb?

With the switch turned on, to prove that this circuit is parallel one could simply remove or unscrew a single light bulb and because the circuit is parallel, the other light bulbs would still be lit.

3.You have 3 light bulbs. Two are connected in parallel. This parallel combination is connected in series with the third light bulb. describe the relative intensity of each bulb. Support your answer.

The parallel light bulbs, the light should be evenly dispersed. Through the series, the light should be dimmer than the others, because most of the light is going towards the parallel so, because basic math 2/3 is more then 1/3.

4.In question number 3, describe the retaliative intensities of the two remaining lit bulbs if one of the bulbs in parallel was unscrewed. support your answer

If one of the parallel bulbs was unscrewed than there is only 2 light bulbs to light, so the intensity levels are about evenly distributed, 50/50. 

Biotechnology and Ethics

Biotechnology and Ethics, for this assignment we had to watch a ted talk, my group choose “What will humans look like in 100 years?” by Juan Enriquez. We took our own separate notes for this presentation, and then came together as a group and went into further research about the topic of prosthetic’s and future advancements. We had spent almost a week gathering as much research as possible in our time frame. With all of that new research and knowledge we created the power points below.

Could a black hole lead to a parallel universe? If not what else could it lead to?

Why is it meaningful?

  • This question is significant to me because it is the unknown, nobody knows what is inside a black hole, one the other side of it, and no one has ever seen one. We don’t know a lot about black holes, because unlike other things we can’t get close to it with either being vacuumed into it or because we can’t find on.
  • I think this question would be important to others because if a black hole leads to an other world, that could have cures for deceases. If we were to access that world, and find things like that, then nobody would ever have to experience losing a friend or a loved one to cancer, or something that they couldn’t control.

Sub Questions

  • What is a black hole made of?
  • What comes out of a black hole?
  • What is a parallel universe?
  • What creates a black hole?
  • If anything went into a black hole (like a satellite) would we be able to track it?
  • How many possible other universes could be out there?

Black Holes, By Freudenrich, Craig; Ghosh Pallab; Malik, Tarik. Published to Gale, Engage Learning on October 6th 2011.

-Blackholes are regions in outer space that no scientist have directly seen one but certain characteristics show that their are certain areas in space where there could be a black hole. Their gravitational pull is so strong that nothing can escape it.

-In 2008, German astronomers indirectly confirmed that their as a black hole at the center of our milky way galaxy.

-There are four types of black holes

  • Stella mass forms when a heavy star collapses under its own weight in a supernova explosion.
  • Super massive are found in the center of galaxies that contain billions of stars.
  • Intermediate, which has a mass thousand times that of the sun.
  • Micro, has the mass of single star

-English physicist Steven Hawking showed in 1974 that every black hole spontaneously and continuously loses a tiny fraction of its mass because of radiation.

-There are enough black holes in the universe that there should occasionally be collisions between them. Such violent events send ripples through the space-time fabric of the universe. Scientists are hoping to soon detect such “gravitational waves” for the first time.

Parallel Universes: Theories and Evidence, by Elizabeth Howell. Published on Space.com May 9th 2018 (08:25 pm)

-13.7 billion years ago, everything in the cosmos was an infinitesimal singularity, the some unknown trigger caused the world to inflate in three-dimensional space.

-With current technology, we are limited by what we discover, and with what we observe, because the universe is curved we are unable to see the outside, if there is an outside

-There are at least 5 theories why a multiverse is possible

  • Infinite Universes, one theory is that the universe is flat and goes on forever. Particles can only be put together in so many Ways, so it is possible that the universe can start repeating.
  • Bubble Universes, “eternal inflation” some areas of space stop Inflating, while others keep getting larger and larger.
  • Daughter Universes, suggests that for every outcome that could come from one of your decisions, there would be a Range of universes, each a different outcome.
  • Mathematical Universes, A mathematical structure is something that you can describe in a way that completely independent of human baggage.
  • Parallel Universes, the idea that space-time is flat.

-Arguing against a parallel universe, the philosophy that it shows how important it is to celebrate being unique. Unless inflation has been occurring for a infinite amount of time, thee are no parallel universes identical to this one.

What happens to objects that enter black holes? by Elizabeth Shockman. Published on September 14th 2015 (8:30 am)

-The information regarding entering a black hole could be discovered by a hologram on the black holes horizon. “For all practical purposes, the information is lost, in a chaotic and useless form.” -Stephen Hawking

-“He was declaring a solution to a problem that he himself invented back in the 1970s, when Stephen Hawking taught us that black holes are not completely black, they give off radiation. Therefore, if you throw something into a black hole, if you drop a planet in, or a book, for that matter, eventually all the information that went in, in the form of that book or that planet or whatever, should come out in that radiation, but no one knows how that could happen.” -Sean Carroll (a theoretical physicist at the California Institute of Technology and author of “The Particle at the End of the Universe.)

-“No one is thinking that you’ll easily just look at the black hole and see what got thrown in … If you were infinitely good at collecting the information and infinitely good at reconstructing it, could you do it? …we used to think that the surface of a black hole was perfectly smooth and featureless, there was no trace of what went inside, and he’s actually saying that maybe there’s some kind of quantum mechanical splotchiness that gets stuck to the edge, to the event horizon of the black hole, from which we can, in principle, read off what made it.”

Information Fluency Questions

  • What questions did you need to research in order to research your topic?

I needed to figure what I was asking before I asked it, one of the questions was “What is a black hole?” I couldn’t have asked a question about black holes if I didn’t know what they were, what makes them, and how they function.

  •  What new or familiar digital tools did you try to use as you worked through this project?

I used the research layout (I don’t know if that counts as a tool but I didn’t use any better ones OK?) I normally don’t use layouts or “planning” sheets unless necessary, but I used it and it saved me probably 3 or more hours of research, so grateful for that.

  •  What was the process you used to investigate the topic?

I kind of just drove right in to the sub questions, because I knew I couldn’t get a straight answer for mine. I answered more of thew sub questions then the main one, but I feel like the sub questions are more helpful towards getting the big question.

  •  How did you verify and cite the information you found?

All of the websites I used, at the top of the page, there was the name of the author(s), title, and when it was published. I did google some of the authors and they seemed professional and legitimate.

  •  How did the process of completing this challenge go? What could you have done better

I thought it went really well, I thought I understood the assignment and what to do. I don’t think there is anything I could do better, If i could do this project again, I would Probably do almost the exact same thing, maybe would’ve added a few more sentences.
