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....

In a recent preprint Riemannian Structures on ℤ₂ⁿ-manifolds, Janusz Grabowski and I initiated the study of Riemannian geometry in the setting of ‘higher graded’ supermanifolds. ℤ₂ⁿ-manifolds are, very loosely, manifolds that have coordinates with a ℤ₂ⁿ-degree (ℤ₂ⁿ := ℤ₂ x ℤ₂ x … x ℤ₂, n-times) and are commutative up to a sign factor that...

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 rotation curves of disc galaxies are flat and dark matter is speculated as explanation. Alternatively, the gravity of material disk could explain the flat curves. Using the gravitational force that a disk exerts on a body in the disk, we have computed the the rotation curves of disc galaxies and the curve of their...

Special relativity does not deal with acceleration, general relativity does not deal with non gravitational acceleration, which leave the theory of relativity imperfect. We will demonstrate some relativistic dynamical laws that specify relativistic acceleration, force and kinetic energy. Also, based on equivalence principle does gravitational mass vary with inertial mass? Newtonian kinematics defines motions of...

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...

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...

I do a detailed analysis of Cantor’s theory of uncountable sets. The logic of his proofs has some weaknesses. I propose an axiom and a solution to continuum hypothesis. The main idea is: Assumption of Cantor’s proofs: All real numbers (set R) are in a list (list L). This assumption means R=L, considering L as...

An analysis of Cantor’s theory of uncountable sets: The logic of his proofs has some weaknesses. Cantor assumes for both his proofs that all real numbers (set R) are in a list (list L). Considering L as a set this assumption assumes R belongs to L. This makes the claim “a real number is constructed...

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 roll, pitch and yaw of an object relative to another is complex to compute. We use 3D complex number to compute them which makes the computation easier and more intuitive. Roll, pitch and yaw are angles of orientation of an object in space and the conversion of these angles among different reference frames is...

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...

Hilbert’s Grand Hotel shows that a fully occupied hotel with infinitely many rooms can accommodate additional guests. But our analyze finds that this is not true. Let us illustrate Hilbert’s Grand Hotel in Figure 1 where each square is a room and is occupied. Suppose that the rooms of the hotel are numbered 1, 2,...

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...

Abstract: The walls of Tokamaks are heavily eroded by plasma which suggests that a mysterious force pushes the plasma to the wall. We have theoretically discovered this force and named it extra-force. This force appears only on single charges but not on current carrying wire, which is why the Lorentz force law does not contain...

By Leo Babauta I talk to dozens of people every month — Zen Habits readers, coaching clients and Fearless Living Academy members — who struggle with a feeling of overwhelm from all of the things on their plates. Overwhelm from tasks, messages, and more is completely normal. It’s based on a fear that we can’t […]

When your 2020 wrapped congratulates you on all four episodes of content you produced this year, it must be PotterCast!

Welcome to season 16, in which we are, we swear, on the edge of actually producing this thing at a normal clip. See how it's going to start to work in this episode in which we introduce a few new segments — a bit of opening chatter (including an IN-Depp conversation as Frankie puts it) with your gang, then two new segments: POTTER PONDERINGS (in this episode, we wonder what it takes to make a Hufflepuff go dark) and HEY NETFLIX (in which we pitch spinoff shows about the Potter universe — today, what would we want from a show about the Ministry of Magic?). Then join us to chat in the drums as usual!

The internet went crazy today when a rumor seemed to break through about the always-destined Harry Potter television show — specifically that while no series is actually in the works, WB is now officially shopping for writers and pitches for an HBO Max event. We did a quick-and-dirty reaction pod with our three hosts and our good friend Proma Khosla, a longtime LeakyCon staffer and Mashable entertainment reporter, to break down the news, what it means for the franchise, and what the fandom does now. 

Basically, we decided the fandom just needs to get a trillion dollars together and buy the franchise from JKR.

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.
