Here are our favorite 7 moments worth sharing with you all –

1. Helicopter in Another Planet

NASA’s highly advanced perseverance rover landed on Mars in February. It resulted in the first-ever aircraft to make a controlled flight on another planet. It was NASA’s solar-powered Ingenuity Mars Helicopter that made headlines in April 2021. The spacecraft will spend the next two years on the red planet.

2. The 5ᵗʰ Fundamental Force

The rate at which the orientation of muons’ magnetic poles lurched was different from theoretical predictions. This is following the research with the experiment with Muon g-2 at Fermilab in Batavia. This odd behavior suggests that some hidden particles are influencing the magnetic properties of muons. It also gives a hint towards the fifth fundamental force.

3. The Detailed View of a Sunspot Ever

A team of scientists from Hawaii captured the most detailed image of a sunspot at the world’s largest solar observatory. The technique of adaptive optics they used, corrects the light distortions created by molecules of our atmosphere. The darkest part of the image reflects the coldest region. For the Sun, the coldest part means 200 times hotter than the room temperature. 

4. Cosmic Hum Detected By Voyager 1

NASA’s Voyager 1 detected a mysterious humming sound in interstellar space, 14 billion miles from earth. This discovery confirmed that interstellar space is not completely vacuum. The persistent “hum” represented the background noise present in the immense regions between the star medium. 

5. The Map of The Dark Matter

A group of 400 scientists obtained the largest ever map of dark matter. The amount of dark matter can be calculated by observing the light that reaches us. Distorted light points towards a huge amount of matter that is bending the light. This is called gravitational lensing. The dark matter magnifies the light from distant galaxies behind it. The map covers the southern hemisphere sky.

6. James Webb Space Telescope Launched

After 30 years of planning and development, we launched the greatest telescope in the history of astronomy. It is headed to a location known as the Second Lagrange point. It took over 27 days to trek the 15,00,000 km distance from earth. It promises to provide a glimpse of the universe as it existed when the earliest galaxies formed.

7. Megastructure Of Galaxies Identified

The galaxy size smudge on the night sky was believed to be the remnant of a long-ago supernova. But a recent study of X-ray data revealed a matching smudge on the other side of the Milky Way. It depicts that there is a pair of galaxy size bubbles 45,000 light-years across. Astronomers believe that it might be the evidence of an eruption million years ago.

These are the most exciting scientific discoveries of 2021. Let’s move forward with the hope that 2022 will be as awesome as 2021.

Fact 1: If you removed all the empty space inside atoms, the entire human race could fit into the volume of a sugar cube.

99.99999% of an atom is empty space. The dense nucleus is surrounded by a cloud of electrons that is spread comparatively over a vast area. Electrons do not exist at one point. They are scattered over a range of probabilities.

Fact 2. When helium is cooled to almost absolute zero, it becomes a liquid with surprising properties.

When helium is just a few degrees below its boiling point of -452°F, it can suddenly do things that other fluids can’t. It can flow against gravity and start running up and down over the lip of a glass container.

Fact 3. A teaspoon full of neutron star would weigh 6 billion tons.

Neutron stars are created when a massive star runs out of fuel. The massive star explodes in a supernova and its core collapses due to gravity. This creates the neutron star.

Fact 4. Winds have shadows.

We know that we can’t see the wind but only can feel it. This is actually not true because wind can cast shadows. They are just not visible to the naked eyes.

Fact 5. Hot water freezes faster than cold water.

This phenomenon is known as the Mpemba Effect. This is because hot water evaporates faster and it reduces the volume left to freeze.

These are a handful of facts that you probably should know. If you know any other amazing physics facts, then tell us in the comments section. (Part – 2 of physics facts is coming soon!)

Albert Einstein passed away on April 18, 1955, at the age of 76 years. He was the most influential physicist of all time. To remember him adequately, well talk about his life in this article, from just a little boy & clerk to the time he changed physics as we know it and his eventual death.

Young Roots

Albert Einstein, son of Hermann Einstein (His father), a salesman and engineer, and Pauline Einstein (His mother), was born on March 14th in Ulm, Germany. Not long after his birth, his family moved to Munich, where young Albert Einstein, learned how to play the violin and the piano (due to his mother’s background). Music was so important to him he once said “If I were not a physicist, I would be a musician. I often think in music, I live my daydreams in music, I see my life in terms of music… I get the most joy in life out of music”.

Albert Einstein spent his teenage years in Munich, having decent grades, but by no means outstanding. He did have, however, remarkable success in mathematics. He enjoyed it so much his father got him a tutor to teach him. In less than a year, though, “his genius was so high I could not follow”, as was later said by the tutor. It’s thought that by the age of 14 Albert Einstein had already mastered integral and differential calculus.

Italy and University

His devotion to the sciences was noted in his admission tests at the Swiss Federal Polytechnic, in Zurich, Switzerland (his family had moved to Milan, Italy, a city relatively close to Zurich, due to financial problems).

He had the highest grades in math and physics but failed in everything else. He spent the following year learning his lacking knowledge in these disciplines, under the guard of Jost Winteler, a professor at the University, and his family. During this year he also met with his first love, Marie Winteler (his professor’s daughter), and renounce German citizenship, to skip compulsory military training.

In the next year, he passed his university exams, although barely passing in Greek and Latin. Here he meets his future first wife, Mileva Maric, the only girl in his class, and one of its top students. Also, in university Einstein rarely frequented classes, preferring to learn the subjects alone in his room. This caused his teachers to alienate him, and it made it very difficult for Einstein to find a job as a professor when he got out of University.

Miracle Year

Due to this difficulty caused by his teachers he went on working as a clerk in the Swiss Patent Office for Intellectual Property in 1901. It was common for Einstein to work on physics, such as writing his thesis for his doctorate, while working at the desk.

In 1905 he finished his thesis and received his PhD. from the Zurich University. During this year he also published 4 articles. The subjects of each article were –

• Photoelectric effect (He would later receive a Nobel Prize in 1921 for this)
• Brownian motion
• Special Relativity
• Equivalence of mass and energy (In this article/research paper, he would first write E=mc², which laid the groundwork for nuclear physics)

It was the 4^th article that made him famous, and he was recognized by Max Planck, known as the father of quantum physics, as a pioneer. From this point on Einstein started receiving dozens of lecture requests, along with teaching positions. During the following years, he worked at various places, such as Austria, Zurich, his alma mater, and Berlin, staying in Berlin from 1914 to 1933.

Time in Berlin

During his time in Berlin, though, lots of things happened. Einstein started an extra-marital relationship with his first cousin, Elsa Lowenthal, which would result in family problems with his current wife, Mileva. Albert Einstein wasn’t already a family man (he rarely spent time with any of his 3 kids, or his wife, for that matter) and these problems culminated in their divorce in 1919. In the same year, Einstein married his cousin, Elsa.

The year 1919 brought even more news though. Einstein’s general relativity (This theory explained that gravity between masses results from their warping of space-time), which Einstein finished in 1916, proved this year during a solar eclipse. You see, according to GR, the light would also be affected by gravity (because of E=mc²), meaning you would be able to see objects that were behind the sun, during a solar eclipse. Two years later he received a Nobel Prize for the photoelectric effect because GR and SR weren’t still completely recognized by the scientific community.

In 1933, when Hitler won the elections in Germany, Albert Einstein went to the USA, bringing along the way a thousand new scientists, to avoid their persecution by the Nazis.

USA and WWII

In the USA, Albert Einstein was appointed as professor of physics at Princeton University, one of the most regarded schools in the world. Here Einstein worked on finding a way to conciliate GR with quantum mechanics, creating a theory of everything, but his quest reached a dead end.

In 1939 he was key for the creation of Project Manhattan, which resulted in the creation of atomic bombs. When two small scientists found what they thought could be a way of constructing an atomic bomb, Albert Einstein signed a petition to call President Roosevelt’s attention. Einstein wasn’t appointed for the project because of public opinion (he was German you see).

In his last months, Albert Einstein deeply regrets this action, saying “I made one great mistake in my life (…) when I signed the letter to President Roosevelt recommending that atom bombs be made.”

Last moments

Einstein eventually passed away in 1955 due to a kidney problem. When the option of operation was recommended, he said “I want to go when I want (…) I have done my share; It’s time to go. I’ll do it elegantly”. His last words aren’t known, because they were in German, and the nurse that was present at the time was American.
