My View- What is Physics? (or Science rather)

Hi guys,

I’m doing another ‘My View’ post. Sorry for not posting any science concepts for so long. I’m working on it.

Why did i choose to write about this? I have been asked this question many many times. Please do note that this definition of physics that i speak of is my own personal opinion and it’s not a universal fact so feel free to comment and voice your opinions!

But just for those who wanted a standard definition:

noun, (used with a singular verb)
1. the science that deals with matter, energy, motion, and force.
Physics is the study of the fundamental ‘things’ that make up and influence everything in the universe and their interactions with each other.

Physics aims to unify everything to get the most fundamental ‘things’ that govern our universe. When I use ‘things’ I mean practically everything. From forces to energy, from matter to antimatter.

And precisely because of the fact that physics is so fundamental that i love it so much.

Allow me to use an analogy, the engineer who knows how every single part of a car is able to understand how to drive the car, but the driver who drives the car does not know how all the different parts of the car work. And this is why physics is so powerful.

It is able to explain the other 2 sciences, chemistry and biology. It can explain how particles interact at the subatomic level, therefore being able to explain things at the atomic level, therefore being able to explain things at the molecular level, therefore being able to explain things at the biological level.

Then aren’t the other 2 sciences useless? NO! Biology and Chemistry are very very important. Despite physics being the most fundamental, biology and chemistry allow us to be much more efficient and be more accurate at the macro level.

Let’s go back to the analogy, if the engineer who knows how the car works but doesn’t know how to drive wants to drive the car. Theoretically he can slowly learn how to control the car by analyzing its most fundamental components. However this would be very impractical as he would have to waste a lot of time to do so.

Biology and chemistry allow us to focus on broader issues while sacrificing breadth for depth. They allow us to be efficient and in the modern society is very very important.

So does that mean that Physics again is useless? Obviously not. Physics is still able to describe other phenomena that occur at the macro scale. Thing such as forces and velocity are still important.

So what is Physics to me?

(After all this is a ‘My View’ post)

Physics is the subject that I love so deeply. The subject that keeps me coming back for more. The subject that never fails to intrigue me. The subject which relieves my stress yet at the same time stresses it out. I hate it yet i love it.

When i first became interested in science, i loved chemistry. I thought that chemistry could solve all my problems. I thought it was the science that made the most sense, until i met physics. In the beginning i found it interesting and i wanted to learn more. However i couldn’t find anyone to teach me the basics. My only source of valuable physics knowledge were my weekly physics classes. I asked questions, many many questions. I asked questions like “Does light have mass?” “What is antimatter” and even engaged in debates with my father and my friends about these concepts.

By this point i was learning something new every week. The pace of which i was absorbing knowledge was increasing steadily too. Then i hit a wall. The questions were getting more and more difficult. I realized that although i was absorbing a lot of information, it wasn’t all useful and it was fragmented. The link between each topic was very vague.

At the end of the year, i received something, something i am thankful for to this day. In the beginning i underestimated its power, until i experienced it for myself. At Cnergy i was learning more than i had ever imagined. It has become the thing i look forward to every Monday. The knowledge i had access to was unbelievable. I was progressing so fast that i found myself being extremely stupid just a few months ago. The friendships i have forged in the Cnergy programme are the most valuable thing i have gained from this programme. Our Cnergy group is extremely tightly bonded.

Cnergy has also given me the opportunity to participate in many various courses and competitions. It has truly enriched my life.

Last but not least, SJPO. The Singapore Junior Physics Olympiad. I have learned so much that its literally indescribable. I am also very thankful for the chance to participate in the trainings.

So back to the question, what is Physics to me?

Other than all the things i have mentioned above, Physics is a path, a journey, a path that i am still walking on.

And I’m never getting off this path.

Unfictioning fiction- Harry Potter Explained?

Hi guys,

Recently I have been participating in quite a few competitions. One of these competitions is the National Junior Solar Sprint Competition (NJSSC). In this competition, groups of 3 students have to build a model car which is entirely powered using solar power. My co-writer, Jackson, participated in this competition with me and we joined as a group of 2. On the night before the actual competition, we were busy fine tuning the car and we were talking about physics at the same time. More specifically, we were talking about higher dimensions and the multiverse theory. At one point in our discussion, I suggested that the magical world of Harry potter could exist should higher dimensions and multiple universes exist. After some discussion we came up with our very own theory/hypothesis and I shall try to explain our hypothesis in this blog post. Before I explain our hypothesis, I will have to explain a few things. Firstly, what is the fourth dimension. Jackson has referred to me a series of videos which explain each dimension from 0 dimensions up to 10 dimensions. The videos can be found at the following channel on YouTube: 10thdim This video is explaining the fourth dimension:

Essentially the fourth dimension is time (or duration rather). We experience it. In the Lorentz transformations (which I will explain in a later blog post) time is the fourth dimension and is represented simply as the character t. Beings in the fourth dimension are able to experience every instant at once. From the start of the universe, to its destruction, all at once.

Secondly, what is the fifth dimension.

The fifth dimension is essentially the many worlds interpretation of the multiverse theory. It is all the possibilities of the universe. All the timelines (4-D timelines) together.

Thirdly, what is the sixth dimension.

As mentioned earlier, the fifth dimension is all the lines together, forming a plane of all the infinite possibilities of the universe. The sixth dimension is the dimension which allows you to jump from timeline to timeline. Similarly, the third dimension allows you to jump from 1 point in a 2-D plane to another point in that same 2-D plane. In this case, the sixth dimension allows you to jump from 1 point in a 5-D plane to another point in that same 5-D plane.

Fourthly, what is the seventh dimension.

This is where it starts to get difficult. The video shows various models of the seventh dimension and how our universe could exist amongst the other versions/individual universes. This part is also key in my hypothesis as it allows us access to a completely different universe as you will read in the final section of the explanation.

Next, what is the multiverse theory. This video is from minute physics. Try to see the link between the many worlds interpretation of the multiverse theory and the fifth dimension.

Essentially, the multiverse theory proposes that there is more than 1 universe. And the many worlds interpretation states that all the possible outcomes actually occur. This is similar to our fifth dimension as all the infinite possibilities occur. As you can see the link between all the dimensions and the multiverse theory. Each 4-D line is 1 separate version of the universe.

Lastly, I have to explain my hypothesis about these universes in the seventh dimension. During the actual NJSSC, I discussed this with my physics teacher who was in charge of me and Jackson during the competition, Mr Tan Teck Nam. I was asking him if the universe is entirely based upon chance due to the fact that quantum physics, which is the most fundamental form of physics, is based upon chance. After the discussion on quantum physics, I questioned classical physics. I asked why does the universe seem to be based on math. Many laws and theories in classical physics are heavily based on math. Such an example would be Newton’s Second Law of Motion, F=ma. Why does force always equal to the product of mass and acceleration and not something else? Why is the value of force predictable? Why does the universe act in such a predictable manner? The answer Mr Tan gave me was that when the universe was created, all the laws and theories and constants were already set. And this also happens in other universes, just that it happens with a different set of laws and constants.¬†Similarly, my hypothesis is that other universes also act in a similar manner, producing different laws and constants.

Now on to the actual theory or more scientifically accurate, the hypothesis.

In our hypothesis, there are humans from the future who develop technologies to enter the seventh dimension thus allowing them to enter different universes and the different 5-D planes within them thus allowing access to all 4-D possibilities of the universe. As they are able to enter the seventh dimension, they can choose which universe to enter. They will choose the appropriate universe¬†and enter it. They also have access to virtually¬†unlimited energy as they can sap energy from the almost unlimited number of universes. So when these people went into other versions of the universe, they captured animals and plants from those universes to our universe (explaining the magical creatures) ¬†Back in our version of the universe, they travel back in time to the modern era rather than their own time (this explains the setting of modern London etc. ). The wand as seen in the books and movies is a device which enables cross dimensional interaction. These humans then left all these wands and stuff in the human world for unknown reasons. Then a few people came along and learnt how to use these magical items and creatures to their advantage. However in our theory there was an accident which resulted in the wiping of memory of these first few ‘wizards’ and ‘witches’. After the memory wipe, they forgot all about regular human stuff (explaining the idea of ‘muggles’) and they believed they were wizards. That is what we believe to have happened that resulted in these wizards and witches in the world of Harry Potter. Now I shall explain some other things which may not seem so apparent.

 

Patronuses and dementors- they are essentially the matter (patronus) and anti-matter (dementors) of another universe. It just so happens that they are animals made up of those two materials and when they come into contact, they will ‘react’ or scientifically speaking annihilate each other releasing energy. Then why does the patronus always win? The wizard that summoned it can keep the portal to its universe/ another universe therefore continuously supplying it with energy and matter. The effect of “dementing” someone is probably due to reactions between the anti-matter and the electrical signals within the brain. The stopping of these signals results in the loss of memories, a common symptom among victims of dementors. Due to the fact that dementors “feed off happiness” it’s also possible that they draw energy from the electrical signals.

 

Horcruxes- each horcrux contains a portal to the owner’s heart/body part therefore whenever it is destroyed, the owner feels pain. The reason why it can only be destroyed by certain items is that only those items are strong enough to destroy the horcruxes (goblin metal is virtually indestructible, fiend fyre is hot enough to melt the horcrux, mbasilisk fangs contain the venom which possibly contains properties that we do not know of). Why does the horcrux seem to contain the owner’s soul? To create a portal to the owner’s heart, a portal to the sixth or fifth dimension is required. It is possible that within these universes, sentient beings are present thus the “soul” is actually the beings within the alternate universe.

 

The Deathly Hallows:

The Elder Wand- I believe that the Elder Wand is a wand crafted by another sentient being within a higher dimension (ie. 5-D, 6-D etc. ). This ¬†is due to the fact that in higher dimensions, more space becomes available. How is this so? Well here’s an example. When we print chips (computer chips of course. Not the crispy snack) we print them on 2-D surfaces. But recently 3-D chips have been invented and these chips are much much much more powerful. Similarly, a 5-D brain would be more powerful than a 3-D one. This explains why the Elder Wand is much more powerful than regular wands.

 

The Resurrection Stone- The stone is much like a horcrux. It contains a portal to a period in the past. This allows the dead to be seen. This portal only allows light and sound to pass therefore the dead can only be seen and heard but not touched.

 

The Invisibility Cloak- It is¬†a sheet which allows¬†light to ‘flow’ around it (or rather bend). Such technologies have been developed and are in the process of further development.¬†This article¬†talks about its recent development and shows how it could possibly be used in the future.

 

Spells:

I’ll explain a couple of spells (definitely not all. I’d be dead).

Protego- Hands down, one of my favourite spells of all time. My theory is it creates a portal to another universe and allows particles from that universe to flow in. Due to the different constants and laws, the particles are extremely strong, dense etc. therefore creating an extremely strong shield.

Avadakedavra- It has the same principle as Protego, however this occurs within the body, causing disruptions in chemical reactions within the body, causing death. As the particles are from another universe, they are unstable and soon decay, causing the cause of death to always be unknown.

 

And with that I have come to the end of this blog post. I hope that you have enjoyed reading it and that you would give me your questions or comments. Do note that the above is a hypothesis and is not a confirmed fact whatsoever.

To end it off with a bang, “Bombarda maxima.”

P.s: Jackson is currently working on a post on Blackbody radiation i.e Quantum physics. Do look forward to that!

P.p.s: We have a surprise for you coming up in a couple of months ūüėČ
