Antimatter: Antimatter consists of the particles, having either a negative Lepton number or a Baryon number. Particles in Normal matter consists of either positive Lepton number or a Baryon number. The two classes of these are known as antiparticle partners of each other.

Some particles with their antiparticles listed are:

  • Electron-Positron
  • Proton-Antiproton
  • Neutron-Antineutron
  • Neutrino-Antineutrino

You may also refer to PhysicsNet for more details about Particles, Antiparticles, and Photons too.

SBC Week 1: My Avatar!

The Student Blogging Challenge (SBC) has started this month, from 6th of October, I will be writing posts relating to SBC. 😄 The first assignment of this week from SBC is to create an avatar and to write a post about it.

This is my avatar! I have created this avatar on this website and it resembles my real look.
I have chosen the pale black/greyish color as my T-shirt, as I like black/greyish outfits personally. I like to wear plain, simple cotton shirts, as they are pretty light and comfortable for me. I actually had the same shirt as this avatar, which was also my one of the favorites.

In the avatar, I have plain, simple hairs, personally I don’t like long hairs, so I usually cut them out when necessary. I have my own specs, which I take special care of. I have an overall nice and simple face outlook, with a small, smile right there. My objective is to remain calm even in situations of trouble, thus a smile best resembles me.
And that is my overall avatar, I can’t make it look as perfect as I look, but I have tried at my best to make it look like that.

Well, that’s it for the first week of challenge from the SBC! I can’t wait for the next week! Comment down your views below. Take care. ^_^.

Beauties in Space

WITCHES AND GIANTS
The man in the Moon may be fiction, but there is a witch in space! The Witch Head Nebula is in the constellation Eridanus, a safe distance of 900 light-years from Earth. With her hooked nose and pointed chin, she glows blue in the reflected light of Rigel, a bright supergiant star.

Fermi Paradox

Image result for Fermi Paradox

I have been reading about this for a while now. I watched a video on YouTube (Kurzgesagt) about this and now I am here to express my views on what could be a massive topic (from point of view for an alien). Where are all the aliens? You should know that alien doesn’t always refer to intelligent lives, it can just be a bacteria somewhere on other planets in the galaxy. However, intelligent lives on other planets can be a thing to reckon with. The universe is appx. 13.8 billion years old. Our galaxy is almost 13.51 billion years old. And then comes our mighty Earth, which is probably 4.543 billion years old. So, according to this time scale, there should have been enough chance for intelligent life to develop in the galaxy itself. But do we see any of them? Do we have any strong evidence of intelligent life in the galaxy? No, right.

One thing I always think about is that there would have been enough time for intelligent life to grow, develop and fade over this period. So, maybe we would have already missed an intelligent life in the galaxy, and we may be on our own in the path of fading as well. What I think is possible is that nature has made it look like already. Intelligent civilizations grow, expand, and then vanish away. This may be the rule of this mighty universe. No civilization can grow beyond this. This is what we call a filter. Or a Great Filter, yeah that. We may have passed away many of them, but a few last and probably undeniable filter is waiting for us, to fade away.

Or, maybe there is some kind of GOD civilization in the universe, which is enough advance in itself that they can cultivate, nourish and then kill other civilizations themselves. So is this possible that some GOD civilization has cultivated life on Earth, they are nourishing it in some manner without us knowing it, and one day they will kill us in a bang, still without us knowing it. Maybe, who knows. Humans don’t know anything, saying this just because, we don’t even know if what we think about The Fermi Paradox is correct or not. Whatever no one cares.

You can watch these Kurzgesagt videos for a piece of more interesting and detailed information about what we have discussed here.

Also a quick note, that I am participating in EduBlogs Student Blogging Challenge 2019, starting from October 6, 2019.

Newton or Einstein?

Image result for newton and einstein

For a very long time, like from my teenage, I believed Albert Einstein as the greatest physicist who ever lived. But a lot of times, I came across people who either disregard this fact or just say “Einstein works are made upon the work did by others”. I didn’t know for a lot of time that Newton didn’t invent the calculus himself. I still don’t know the actual thing or the controversy about that, but it may help you. Also while discussing this with a few of my friends, I came to understand that you can’t say that a particular person is greatest just with his works, you have to consider his ideas and how did they affect the world. Here is an excerpt from what my friend quoted himself in the discussion.

Quoting Eugene Wigner –

"I have known a great many intelligent people in my life. I knew Planck, von Laue and Heisenberg. Paul Dirac was my brother in law; Leo Szilard and Edward Teller have been among my closest friends; and Albert Einstein was a good friend, too. But none of them had a mind as quick and acute as Jansci [John] von Neumann. I have often remarked this in the presence of those men and no one ever disputed.

But Einstein's understanding was deeper even than von Neumann's. His mind was both more penetrating and more original than von Neumann's. And that is a very remarkable statement. Einstein took an extraordinary pleasure in invention. Two of his greatest inventions are the Special and General Theories of Relativity; and for all of Jansci's brilliance, he never produced anything as original."

I think this really makes sense, or not? Well, I don’t know. But still, Isaac Newton had worked a lot in the field of mathematics and his contributions are more than just ideas that affect the world. Without him, Einstein wouldn’t have been able to work on gravity himself and derive furthermore new ideas. Also got to know from a friend that, Einstein was named by the TIME, the most important person of the century. Well, that makes sense this time around. My other friend said that Newton has worked in a lot of fields. Yeah, that’s true. He laid to the foundation for many things.

Well whatever the things are, I believe saying “The greatest physicist of all time” for Einstein and saying “Newton contributed less to what his counterparts did” for Newton are both wrong. They were the inspiration to a lot of people, other physicists, and yeah, their work did help a lot and is helping the modern-day people. They both were the greatest of their times, and yeah, they were, for sure.

One Giant Post

That’s one small step for a man, one giant leap for mankind.

On 20th of July, 1969, MANKIND saw human being for the first time ever, stepping on the soil other than that of EARTH.

Neil A. Armstrong, Commander; Michael Collins, Module Pilot; Edwin E. “Buzz” Aldrin, Lunar Module Pilot, went on a mission that shaped the future of Space Exploration that everyone saw coming after Neil A. Armstrong became the first human being ever to step and walk on an alien land for the first time ever. He with Edwin E. “Buzz” Aldrin were the first humans to walk on the MOON. They spent several hours there, collecting samples, clicking pictures, and most importantly leaving behind a plaque in commemoration of the historic event.

This is a replica of the plaque which the Apollo 11 astronauts will leave behind on the moon in commemoration of the historic event. The plaque is made of stainless steel, measuring nine by seven and five-eighths inches, and one-sixteenth inch thick. The plaque will be attached to the ladder on the landing gear strut on the descent stage of the Apollo 11 Lunar Module (LM). Covering the plaque during the flight will be a thin sheet of stainless steel which will be removed on the lunar surface.

Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by President John F. Kennedy: “before this decade is out, of landing a man on the Moon and returning him safely to the Earth.”
It was a huge-huge achivement in the process of exploring space beyond any leaps and bounds. People all around the world gathered to view this historic event on the television.

It was a huge inspiration for the further missions that took place. “This mission also directly indicated that the moon is now in the reach of humans, meaning we now have set eye to explore more about life in space.”
All the three astronauts came back home on 24th of July, 1969, safely landing in Pacific Ocean. They were welcomed like stars in the country as people awaited them to share their experience with the world.
On the occasion of this historic aniversary, relive that moment from the words of Michael Collins, Module Pilot, in this very-very special doodle from Google.

On the 50th aniversary of the Apollo 11 landing, I wish everyone, go celebrate this historic day, with proud that humans are now ready to set foot on MARS, and to make it another GIANT LEAP FOR MANKIND.
Thank you, and cheers (ALL GIANT PEOPLE OUT THERE).

Gravity:- Gravity is derived from a Latin word gravitas, meaning ‘weight’, also refers to gravitation, is a natural phenomenon by which all things with mass or energy, including all planets, stars, galaxies, and even light, are brought towards one another.


Also, a very happy International Earth day. We owe our everything to our mother earth, help each other, protect it.
