I find that in theory the weird Speed Boost of the interstellar object ‘Oumuamua should be 0.217 mm/s above the prediction and that ‘Oumuamua should slow down less than prediction, in proportion of which the difference is 4.28×10-8 near the Sun. For Pioneer anomaly I have computed the gap between real and predicted acceleration and...

Above is an image of “dry ice spiders” on Mars. Every spring the Sun warms up the Martian south polar icecap and causes jets of carbon-dioxide gas to erupt through the icecap. These jets carrying dark sand into the air and spraying it for hundreds of feet around each jet forming these wonderful spider-like structures....

Orbit equation and orbital precession General Relativity explains gravity as Space-Time curvature and orbits of planets as geodesics of curved Space-Time. However, this concept is extremely hard to understand and geodesics hard to compute. If we can find an analytical orbit equation for planets like Newtonian orbit equation, relativistic gravity will become intuitive and straightforward...

In this article, we derive the gravitational time dilation factor in a new manner, which allows us to identify the mathematical cause of Schwarzschild radius, to give a theoretical way to avoid it and to compute properties of black hole. General relativity effects are computed as simple as in special relativity. Observability of black hole...

The orientation of body in space is defined 3 by angles. The step by step rotation process and chain of three-dots multiplication give an easy way to compute pile of rotations in 3D and high dimensional space and give a general orientation system. A visualization of quaternion is proposed. The orientation of a rigid body...

Multidimensional complex systems with 3, 4 or more dimensions are constructed. They possess algebraic operations which have geometrical meanings. Multidimensional complex numbers can be written in Cartesian, trigonometric and exponential form and can be converted from one form to another. Each complex numbers has a conjugate. Multidimensional complex systems are extensions of the classical complex...

Today’s methods for computing orientation are quaternion and rotation matrix. However, their efficiencies are tarnished by the complexity of the rotation matrix and the counterintuitivity of quaternion. A better method is presented here. It uses complex multiplication for rotating vectors in 3D space and can compute orientation without angle and trigonometric functions, which is simple,...

For Newtonian mechanics The Schwarzschild radius is the radius of the event horizon of a black hole. Amazingly, we can compute it with Newtonian mechanics, which is explained below. Consider a big mass M which creates the gravitational acceleration a for a small mass m at the distance r from M, see figure 1 and...

Cantor’s diagonal argument claims that ℝ is uncountable. When we see real numbers as points on the number line, we can put a name on each point and put the names into a list without contravening Cantor’s diagonal argument because we cannot create a diagonal from a list of names. However, we do not need...

The apparent non‑gravitational acceleration the extra-solar-system ‘Oumuamua exhibits is puzzling. We find that when the position and velocity of the Sun is correctly set in computing the predicted orbit, ‘Oumuamua’s trajectory can be explained with gravity and we have reproduced the unexpected gap by computation. We also propose to search for new extra-solar-system high speed...

This is one of those portraits generated by Midjourney, not that of a real person.Like many people I’m impressed with the facility of Midjourney to create portraits of photogenic people.

Abstract: The Lorentz force law is fundamental for electromagnetism. However, it is known long ago that the Lorentz forces between two current elements do not respect the Newton’s third law. This seemingly harmless flaw had never been corrected. In physical sciences a discrepancy often hides in it new understanding or unexpected breakthrough. For solving this...

What even is this planet that we live on anymore though?

It turns out that there's a VERY fine line between Donald Trump and the Futurama character Zapp Brannigan. Memes with Zapp's image and Trumps tweets started circulating the internet and they caught the attention of Billy West, the voice actor who plays Zapp Brannigan on Futurama. The recordings he made are out of this world.

Do you use Google Chrome? Do you want to look at pictures of kittens instead of Donald Trump? Install this! It doesn't work on every news site, but it's still pretty darn great. PS - If you already have the extension installed and you're trying to look at these examples, they'll all be replaced with kittens. It's magic!

It's every cat's greatest dream to finally catch that red dot. And sometimes they do (meaning we get tired of holding down the laser and pointing). 

The arm was created by Enabling the Future, which has a chapter at Sienna College in Albany, New York. For its first project the Siena e-NABLE group made an Iron Man-themed hand for 5-year-old Jack Carder in Ohio.



In this case, nine-year-old Karissa Mitchell's (who was born without a right hand and most of her wrist) mother reached out to the group on campus, Siena College's director of marketing and communications said.

"She's watched the movie at least 100 times. We sing the songs all the time. We even have a karaoke machine that's 'Frozen'-themed," said Karissa's mother. The prosthetic was built using a 3-D printer and is comprised of 30 parts (it took near 30 hours to make).

To help Karissa achieve her dream of becoming a Disney princess, the team used "a pretty transparent ice blue color filament and added snowflakes to the forearm and her name with an Elsa crown on the cuff," said Alyx Gleason, the project lead and president of Siera e-NABLE. The arm also came with an Olaf LED light source.

Anyone who is in need of an arm or hand is encouraged to reach out to Siena e-NABLE.

Everyone likes the smell of their own brand.

But why do you like torturing innocent bystanders of your disgusting gas? Honestly, being subjected to your farts should be considered torture. Liking your farts is akin to waterboarding. You're a war criminal. You and your farts should sit before an international tribunal. 

Yes, you. 

Anyway, this video explains why you're such a sicko. ASAP Science continues to do great work in under five minutes.
