Scroll down and you can cruise along the icy rings of Saturn. This high resolution scan is a mosaic of images presented in natural color. The images were recorded in May 2007 over about 2.5 hours as the Cassini spacecraft passed above the unlit side of the rings. To help track your progress, major rings and gaps are labeled along with the distance from the center of the gas giant in kilometers. The alphabetical designation of Saturn’s rings is historically based on their order of discovery; rings A and B are the bright rings separated by the Cassini division. In order of increasing distance from Saturn, the seven main rings run D,C,B,A,F,G,E. (Faint, outer rings G and E are not imaged here.) Four days from now, on November 29, Cassini will make a close flyby of Saturn’s moon Titan and use the large moon’s gravity to nudge the spacecraft into a series of 20 daring, elliptical, ring-grazing orbits. Diving through the ring plane just 11,000 kilometers outside the F ring (image bottom) Cassini’s first ring-graze will be on December 4.
Day 3 [3.2.17]: Favourite study methods
I like to make electronic notes, then I rewrite them out (my chemistry notes are in the shot) and also make flip cards with my daiso word cards! I enjoy using mildliners/any highlighters to make it look pretty, but notes are mainly for memorising. (Practicality > aesthetic)
Quantum Entanglement - The Quantum Source of Space-Time. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently - instead, a quantum state must be described for the system as a whole. Quantum mechanics governs the world of the small - the weird realm in which particle can be in many places at the same time, and can simultaneously spin both clockwise and anticlockwise. Gravity governs the Universe at large - from the fall of an apple to the motion of planets, stars and galaxies. The theory holds that gravity is geometry: particles are deflected when they pass near a massive object not because they feel a force but because space and time around the object are curved. Both theories have been abundantly verified through experiment, yet the realities they describe seem utterly incompatible. And from Van Raamsdonk standpoint, all that’s needed is ‘entanglement’: the phenomenon that many physicists believe to be the ultimate in quantum weirdness. Entanglement lets the measurement of one particle instantaneously determine the state of a partner particle, no matter how far away it may be - even on the other side of the Milky Way. In conclusion, it seems that entanglement is the essential ingredient that knits space-time together into a smooth whole - not just in exotic cases with black holes. If any two particles are connected by entanglement, the physicists suggested, then they are effectively joined by a wormhole. And vice versa: the connection that physicists call a wormhole is equivalent to entanglement. They are different ways of describing the same underlying reality.
08.12.2017; my arabic exam is really close, so i must start working harder now. i don’t think i’ll do great because i’m way behind my classmates (i joined the class two months later than them), but i feel like i’m learning so much, i feel way more confident with the language now, and it makes me so happy ♡
also, i started a new book under my father’s recommendation: ‘the seven minutes’ by irving wallace.
Timeline of the Far Future. While scientific predictions of the future can never be absolutely certain, present understanding in various fields allows for the prediction of far future events, if only in the broadest strokes. These fields include astrophysics, which has revealed how planets and stars form, interact, and die; particle physics, which has revealed how matter behaves at the smallest scales; evolutionary biology, which predicts how life will evolve over time; and plate tectonics, which shows how continents shift over millennia. All projections of the future of the Earth, the Solar System, and the Universe must account for the second law of thermodynamics, which states that entropy, or a loss of the energy available to do work, must increase over time. Stars eventually must exhaust their supply of hydrogen fuel and burn out. Close encounters gravitationally fling planets from their star systems, and star systems from galaxies. Eventually, matter itself is expected to come under the influence of radioactive decay, as even the most stable materials break apart into subatomic particles. Current data suggest that the universe has a flat geometry (or very close to flat), and thus, will not collapse in on itself after a finite time, and the infinite future potentially allows for the occurrence of a number of massively improbable events, such as the formation of a Boltzmann brain. This timeline coverS events from roughly eight thousand years from now to the furthest reaches of future time. A number of alternate future events are listed to account for questions still unresolved, such as whether humans will become extinct, whether protons decay, or whether Earth will survive the Sun’s expansion into a red giant.

Hello everyone! Since my second semester of college has started, I decided to start a bullet journal. It’s definitely a work in progress but I’m doing my best :)
week eleven, semester two: a moodboard this week consisted of stressing out about tests (i got 86% on one!), marathoning queer eye, and drinking matcha frappes✨
🎶listening to: healing - seventeen
