if a professor brags about how hard it is to pass their class then drop the class. they should not be proud of being bad at conveying information to students. you’re not paying thousands of dollars to fail. find a professor that wants you to pass.

I would love to study here

A little bit of London wandering, and a treat I brought home for myself 🍪

Hogwarts Houses Aesthetics

Gryffindor- holding rocks from the beach in yours hands, watching them flow out, being at the playground at midnight with your best friends, completing dares that no one even dared you to do, running just for the purpose of doing something, sending your best friend appreciation paragraphs for them at 3:00 A.M., going on roller coasters very confident but freaking out a little when you get to the top, playing ghosts in the graveyard with you or friends at 11:00 A.M., putting on makeup and dressing up even though you have nowhere to go, dancing and lip syncing in your room crazily, finding wonders in the little things, spacing out, diving in right away in the lake, handing out feminism badges, walking at a regular pace in the rain with your arms out, forming new clubs, being overly-excited, making small designs on the misty car window, either taking 0 selfies or 1938284 at a time, red lipstick and black mascara, scraped up legs

Hufflepuff- sugar highs, putting so much trust in your friends, dressing up as your favorite book and tv show characters, growing out your hair, blueberry pancakes when you wake up, whether that’s at 6:00 A.M. or 12:00 P.M., catching fireflies, the feeling you get when you make all your friends fall over laughing, seeing a spiny chair and immediately know what you will be doing for the rest of the day, ice cream bigger than your head, putting flowers in your friend’s hair, being the last to finish your popsicle, getting excited when you hear the ice cream truck, heart-shaped sunglasses, petting every puppy you see on the street, making a big deal out of everything, getting your friends presents even though there is no special occasion, candy shops, slumber parties, writing songs, writing stories, musicals and Broadway plays, caring about others more than you care about yourself, strip malls, taking pictures of your friends, happy drunk, defending the underdog, finding beauty in everyone’s eyes

Ravenclaw- record shops, when your face gets red after you get complimented, chokers, laughing when your nervous, cuddling with your friends at 2:00 A.M., drinking coffee in the morning, going to the beach when the waves are crazy, telling yourself to only read one more chapter but you end up finishing the book, writing letters to the author, scented candles, knee high socks, taking videos so you can remember the moment, perfect makeup techniques, laying on the rooftop at 3:00 A.M., looking at the stars, making multiple playlists for different moods, watching documentaries, playing mindlessly with your friend’s hair, eating a three course meal at 12:00 A.M., pranking your friends when they’re sleeping, putting your headphones on long car rides, binge watching Netflix, spending your day at the library, asking your friend to go to the bathroom with you, getting a churro at the fair, studying because you want to, not because anyone else wants you to

Slytherin- testing the limits, fire whiskey, mysteries, the sound of the thunderstorm against your window while you are drifting to sleep, doing anything for your friends, talking back to the teacher, smirking against the classroom, splashing the people who think the water is too cold in the lake, escaping reality, black roses, rooting for the underdog, downtown, skyscrapers, doing anything to get your way, cat ears headband, correcting people’s grammar, solving moral dilemmas easily, fixing your best friend’s makeup in the school bathroom, leather jackets, playful smirks, making faces across the classroom, knowing what your friend is saying just by reading their expression, self-deprecating humor, the moon, looks that could kill, playing sweet and sour with your close friends, doing everything yourself, with no help, rewriting history, chopping a little bit or a lot of your hair off, dirty jokes, sleepless nights, being the hero to your class because you found all the answers online, knowing when to stop but not stopping anyway

Praying for the woman I’ll be in 5+yrs I hope she’s happy, and loved, living life unapologetically, doing what she loves.

Geometry Matters. But why?

The contribution of geometry to the evolution of human and natural sciences is a well established fact. Since the Greeks started to realize that the argument is more powerful when backed up by empirical evidence, rather than previous experience, all sciences started to benefit from an approach that had something new: a system of thought. And that system was based on definitions and axioms given by geometric laws. For example, Pythagoras defined reality with three basic principles, extracted from geometric knowledge:

1. Some propositions must be accepted as true without being demonstrated.

2. All other propositions of the system are derived from these.

3. Their derivation must be formal and independent from the subject at matter.

And since for Pythagoras the things are an imitation of the numbers, their definitions and axioms, will reflect the universe, provide intangible harmony and build visible beauty.

The improving of left-right brain connections.

Most activities engage only one hemisphere of the brain and its corresponding functions: the left for language, hearing, logic and mathematics; the right for spatial recognition, images and music processing, symbolism and so on. By requiring both analytical thinking and spatial visualization, geometry activates processes that engage both sides of the brain at the same time, in resolving a given task. When picturing a cube, for example, the brain is tasked with recognizing spatial properties of the cube (height, depth etc) while maintaining its overall shape (by calculating its angles or the length of its segments). This leads to an elevated number of connections between the brain hemispheres, having a long-term benefit in the overall critical thinking or imagination of the geometry user.

The continuous visual representation of truth.

Because of the early traditions and methods of orally sharing and debating knowledge, the first visual (geometrical) representations of mathematical concepts where being drawn by scribes, sometimes directly when hearing a particular information.  This process was flawed, given that the person drawing did not posses geometric knowledge, thus leading to miss-interpretations and errors in the visual representation. In the early 300’s Euclid becomes aware of this error and begins drawing his own definitions and axioms, developing adjacent texts that can be understood by any mathematician or artist, for that matter.

And, with the introduction of the visual perspective by Leon Battista Alberti, the geometrical diagrams and laws became general accepted when depicting a mathematical truth or any given representation of reality.

Thus, geometry provides continuity in visual communication in general, and a context in which all individual things can be represented, calculated and later better understood.

The creation of visual reality.

The perception of the visual information and its abstract notions is connected to the perception of reality. As many others, Rudolph Arnheim shows how visual information is being formed by the perception of the new and by the memory of the old, showing a continuance in the cognitive process. And since all information has geometric properties when closely analyzed (height, weight, depth, curvature etc), geometry will be present in all aspects of the visual reality.

The perception of beauty and harmony in things.

If what is above is also below, geometry can be a mirror for these two dimensions. While symmetry defines what geometry is, geometric proportions and ratios define man’s perception of beauty and harmony. A harmonic state is associated with an element or an object having its inner components in perfect equilibrium.

Thus, nature is being perceived as beautiful and its creator, good. For example, the complex relation between symmetry and aesthetics is shown in how symmetry defines the perceived qualities of the human body and how these traits are a sign of good health or good genetic conditions.

Man uses beauty as an indicator of truth and while beauty is truth (Ian Stewart), symmetry, proportion and simplicity will define it.

While many of the elements of nature have an innate geometric structure - water, sound or even light - the more complex architecture of the perceived or the hidden dimensions of reality rely on very complex laws that have different types of shapes, boundaries, behaviors and interactions with the micro and the macro elements of the universe.

In analyzing these dimensions and interactions, many sciences rely on geometric studies and developments that generate universal accepted answers. For example, in his famous special relativity theory, Einstein describes the dimension of space-time by creating a coordinate system that fixes and standardizes measurements, in order to specify the relationship between a moving observer and the phenomenon or phenomena under observation.

The place of humans in space-time.

By placing man in the middle of all created things, human consciousness becomes a necessity of life. An antropocentric perspective explains why the universe has an age. Why the universe works at these exact parameters that an objective observer discovers. That we discover.

Thus, man connects himself to the main elements of the universe: the space-time and the fundamental laws of physics, geometric defined aspects of reality, that man can relate to, explore and evolve upon.

The geometric laws and ratios that nature confides in, are also bound to shape human existence. The human body, the human mind and their correspondent dimensions and proportions have geometric properties and attributes, similar to all other elements of nature.

The universal geometric code

The geometric code of information is inherent to nature, inherent to human consciousness and is present in all perceived and created forms, in the tangible and the intangible.

And maybe a reality built under the auspices of geometry is desirable, being a discipline developed with attention along several millennia and with which the greatest minds of history have created concepts, objects, religions and even the entire universe.

1 multiplies itself and creates 2. The paradigm of reality is the result of the conscious observation. If the system from which consciousness takes part is abstract, then reality is an abstraction of this, by reflecting itself and creating form.

Why Bennu? 10 Reasons

After traveling for two years and billions of kilometers from Earth, the OSIRIS-REx probe is only a few months away from its destination: the intriguing asteroid Bennu. When it arrives in December, OSIRIS-REx will embark on a nearly two-year investigation of this clump of rock, mapping its terrain and finding a safe and fruitful site from which to collect a sample.

The spacecraft will briefly touch Bennu’s surface around July 2020 to collect at least 60 grams (equal to about 30 sugar packets) of dirt and rocks. It might collect as much as 2,000 grams, which would be the largest sample by far gathered from a space object since the Apollo Moon landings. The spacecraft will then pack the sample into a capsule and travel back to Earth, dropping the capsule into Utah’s west desert in 2023, where scientists will be waiting to collect it.

This years-long quest for knowledge thrusts Bennu into the center of one of the most ambitious space missions ever attempted. But the humble rock is but one of about 780,000 known asteroids in our solar system. So why did scientists pick Bennu for this momentous investigation? Here are 10 reasons:

1. It’s close to Earth

Unlike most other asteroids that circle the Sun in the asteroid belt between Mars and Jupiter, Bennu’s orbit is close in proximity to Earth’s, even crossing it. The asteroid makes its closest approach to Earth every 6 years. It also circles the Sun nearly in the same plane as Earth, which made it somewhat easier to achieve the high-energy task of launching the spacecraft out of Earth’s plane and into Bennu’s. Still, the launch required considerable power, so OSIRIS-REx used Earth’s gravity to boost itself into Bennu’s orbital plane when it passed our planet in September 2017.

2. It’s the right size

Asteroids spin on their axes just like Earth does. Small ones, with diameters of 200 meters or less, often spin very fast, up to a few revolutions per minute. This rapid spinning makes it difficult for a spacecraft to match an asteroid’s velocity in order to touch down and collect samples. Even worse, the quick spinning has flung loose rocks and soil, material known as “regolith” — the stuff OSIRIS-REx is looking to collect — off the surfaces of small asteroids. Bennu’s size, in contrast, makes it approachable and rich in regolith. It has a diameter of 492 meters, which is a bit larger than the height of the Empire State Building in New York City, and rotating once every 4.3 hours.

3. It’s really old

Bennu is a leftover fragment from the tumultuous formation of the solar system. Some of the mineral fragments inside Bennu could be older than the solar system. These microscopic grains of dust could be the same ones that spewed from dying stars and eventually coalesced to make the Sun and its planets nearly 4.6 billion years ago. But pieces of asteroids, called meteorites, have been falling to Earth’s surface since the planet formed. So why don’t scientists just study those old space rocks? Because astronomers can’t tell (with very few exceptions) what kind of objects these meteorites came from, which is important context. Furthermore, these stones, that survive the violent, fiery decent to our planet’s surface, get contaminated when they land in the dirt, sand, or snow. Some even get hammered by the elements, like rain and snow, for hundreds or thousands of years. Such events change the chemistry of meteorites, obscuring their ancient records.

4. It’s well preserved

Bennu, on the other hand, is a time capsule from the early solar system, having been preserved in the vacuum of space. Although scientists think it broke off a larger asteroid in the asteroid belt in a catastrophic collision between about 1 and 2 billion years ago, and hurtled through space until it got locked into an orbit near Earth’s, they don’t expect that these events significantly altered it.

5. It might contain clues to the origin of life

Analyzing a sample from Bennu will help planetary scientists better understand the role asteroids may have played in delivering life-forming compounds to Earth. We know from having studied Bennu through Earth- and space-based telescopes that it is a carbonaceous, or carbon-rich, asteroid. Carbon is the hinge upon which organic molecules hang. Bennu is likely rich in organic molecules, which are made of chains of carbon bonded with atoms of oxygen, hydrogen, and other elements in a chemical recipe that makes all known living things. Besides carbon, Bennu also might have another component important to life: water, which is trapped in the minerals that make up the asteroid.

6. It contains valuable materials

Besides teaching us about our cosmic past, exploring Bennu close-up will help humans plan for the future. Asteroids are rich in natural resources, such as iron and aluminum, and precious metals, such as platinum. For this reason, some companies, and even countries, are building technologies that will one day allow us to extract those materials. More importantly, asteroids like Bennu are key to future, deep-space travel. If humans can learn how to extract the abundant hydrogen and oxygen from the water locked up in an asteroid’s minerals, they could make rocket fuel. Thus, asteroids could one day serve as fuel stations for robotic or human missions to Mars and beyond. Learning how to maneuver around an object like Bennu, and about its chemical and physical properties, will help future prospectors.

7. It will help us better understand other asteroids

Astronomers have studied Bennu from Earth since it was discovered in 1999. As a result, they think they know a lot about the asteroid’s physical and chemical properties. Their knowledge is based not only on looking at the asteroid, but also studying meteorites found on Earth, and filling in gaps in observable knowledge with predictions derived from theoretical models. Thanks to the detailed information that will be gleaned from OSIRIS-REx, scientists now will be able to check whether their predictions about Bennu are correct. This work will help verify or refine telescopic observations and models that attempt to reveal the nature of other asteroids in our solar system.

8. It will help us better understand a quirky solar force …

Astronomers have calculated that Bennu’s orbit has drifted about 280 meters (0.18 miles) per year toward the Sun since it was discovered. This could be because of a phenomenon called the Yarkovsky effect, a process whereby sunlight warms one side of a small, dark asteroid and then radiates as heat off the asteroid as it rotates. The heat energy thrusts an asteroid either away from the Sun, if it has a prograde spin like Earth, which means it spins in the same direction as its orbit, or toward the Sun in the case of Bennu, which spins in the opposite direction of its orbit. OSIRIS-REx will measure the Yarkovsky effect from close-up to help scientists predict the movement of Bennu and other asteroids. Already, measurements of how this force impacted Bennu over time have revealed that it likely pushed it to our corner of the solar system from the asteroid belt.

9. … and to keep asteroids at bay

One reason scientists are eager to predict the directions asteroids are drifting is to know when they’re coming too-close-for-comfort to Earth. By taking the Yarkovsky effect into account, they’ve estimated that Bennu could pass closer to Earth than the Moon is in 2135, and possibly even closer between 2175 and 2195. Although Bennu is unlikely to hit Earth at that time, our descendants can use the data from OSIRIS-REx to determine how best to deflect any threatening asteroids that are found, perhaps even by using the Yarkovsky effect to their advantage.

10. It’s a gift that will keep on giving

Samples of Bennu will return to Earth on September 24, 2023. OSIRIS-REx scientists will study a quarter of the regolith. The rest will be made available to scientists around the globe, and also saved for those not yet born, using techniques not yet invented, to answer questions not yet asked.

Actual advice on how to study for engineering courses from a first year student

Okay so I just finished my first semester in university and lets just say I’ve got to change my whole learning/studying style to be able to survive here. Here are some of the things I’ve learnt to do and will be doing in second semester:

1. Start backwards:

 I highschool, you try to learn the subject by going to class, listening to the teacher, then going home, reading the textbook, then doing the homework, then making notes, then studying for the final. In engineering, you have to do this backwards: You will realize that you are going to be basically teaching yourself the content one way or another soon before the finals, so better start now. First, go through the past exams and past papers - make a list of all the major topics covered (example: if in an electrical circuits course, a question on a past final exam is “find the equivalent circuit using thevenin’s theorem” then write Thevenin’s theorem as a topic to be learned). Then go on youtube and find videos that explain each of these topics to you and make rough notes on these topics. (Reblog if you want me to make a master list of all the youtubers that teach engineering really well). Then go through he textbook and find sample questions not he theorem/topic you learnt off of youtube, and solve them. Then write your doubts in a notebook. Then go to class and have two notebooks open : one where you are taking notes of what the prof is saying, and one which has your practice problems solved, and see if the prof clarifies your doubts in the lecture. The lecture should be review of what you learnt at home!!!! Then, after class go to the prof and clarify any doubts. Then go home and make final notes on the topic. I like to make notes on cue cards (more on this later). Then go back to the final exam and see if you can solve the problem.

2. Make cue cards:

I like to get index cards and write a short note on how to solve each type of question I am likely to see on a final exam on each question card. Example: one cue card for “how to find resistance using wheatstone bridge” . I link the cue cards with a clip and its easier to carry the around and study.

3. Get pretty notebooks and organize your stationary. Its easier to stay focused when everything is pretty. 

“Decide that you want it more than you are afraid of it. Decide, commit, succeed.”

— from the little voice that knows that you can do it.
