In this post, I’m going to talk about the study methods that have worked for me and that I learned during my time at UCLA!

(see another post like this about being healthy here)

Short Term Productivity

Use a stickynote/index card and write a couple goals for today only. Don’t write too many or you will feel overwhelmed! Stick it on your laptop or planner or notebook (somewhere you will see it)

Have a whiteboard at your desk and write down things you need to remember (like a simple equation or some vocab)

While waiting for something (the bus, your coffee, the shower to warm up) have something to recite in your head (probably something you already know, but would like to reALLY KNOW)

When you read, try to tie big concepts to things you would remember easily (like acronyms or symbols) like for example i remember gen chem oxidation as OIL RIG: Oxidation is Loss (of electrons) and Reduction is Gain (of electrons) and I remember the first four unordinary hydrocarbons from Me Eat Peanut Butter (lmao): Methane, Ethane, Propane, Butane

Longer Term Productivity

Plan out your weeks!!! Plan when you will study on each day of the week and keep track of due dates

Make it a habit to do homework/assignments AS SOON AS YOU CAN (like right after you snack or something after classes)

Try not to think about how long you will study and rather think about the number of topics you will study

Don’t stop until you feel confident in your knowledge OTHERWISE YOULL JUST LOSE IT IT ALL

Keep your notes organized because you never know when something is gonna bite you in the butt again in the future

Review everyday. Like, Serioouslyyyy. It helps a lot.

Read before going to bed instead of being on your phone for 400 hours :C I THINK ITS TRUE THAT THE STUFF YOU READ BEFORE BED STAYS WITH YOU BETTER BC YOU GET TO SLEEP ON IT

Try to keep your area quiet or have only white background noise because if someone is talking about the weather and you’re studying math, best believe you’ll only remember the weather

Reading a Textbook

Most of the time, you don’t need to read the introduction paragraphs.

Read the bolded titles to see what you will be getting into

Before class you can skim lightly!! It will help you not feel lost in class

AFTER CLASS you will now FOCUS YOUR READING ON WHAT WAS SAID IN CLASS because most of the time, class-covered topics ARE THE MOST IMPORTANT! save yoself some time!!

When reading after class, do NOT just read. If you go over something that makes you go ??? in even the slightest way, read it again to understand. Look it up. Do it in THAT moment because you’re gonna forget to do it later.

If you don’t wanna read the whole darn book because ur lazy (like me) or you are cramming, READ!! THE!! SUMMARY!!!

The back of the book might have some seriously useful appendixes

Try not to skip the diagrams and pictures lol they’re there for a reason

Taking Notes in Class

dont be on your phone or whatever during class time Like actually PAy attention because if you learn it now, you won’t have to try to learn it again later (you can be on your phone later)

Take down everything written on the boards FOR SURE because if the professor/teacher thinks it’s important to write it, you better think it’s important too

Be an engaged listener! Don’t let it slide straight thru ur head

Try not to scribble your notes so you can read it later

Make CLEAR HEADERS for the topics so you can find those notes quickly

Def make friends in class in case you miss something on the notes ://

Doing Practice Problems and Homework

Get yoUR HOMEWORK DONE FIRST OF ALL

Homework is seriously a great study tool because your instructor assigned that FOR A REASON (aka it’s prob gonna be tested on)

Try to know what you are doing before you start the homework so that you don’t feel lost as heck doing it

When doing practice problems, if you have the answers, don’t be afraid to look at the answer the first time around if you don’t know how to do it. IVE SELF TAUGHT MYSELF SOOOOO MUCH by just looking at the answer to a question.

DONT RELY ON THE ANSWERS THO

Don’t memorize how to do the practice problems, you should memorize the method of solving the problem and understand each step clearly (and understand WHY you do that step!!!) just in case the test pulls some funky stuff on you

The more you can do, the better. But don’t be sleepy and do them because you won’t really retain anything

Other Random Things

My organic chem professor actually did a funny study on sleep and test scores. He said on his final exam he asked “How many hours of sleep did you get last night?”

and like obviously the more hours of sleep reported, generally the higher the student scored on the exam

SLEEEEPING IS GOOD FOR YOUR LEARNING

WHEN YOU SLEEP AND HIT THE REM CYCLE, YOUR BRAIN PROCESSES THE INFORMATION BETTER and it will really stay with you. So yall need to sleep. Don’t do the all nighters. You won’t remember anything

anyways like nike you should Just Do It

I hope you guys find this useful!! Remember that everyone has different needs and preferences, so take these tips as just tips and not rules!! Experiment with things, see what you like best, see what gives you the best scores.

Good luck with everything~ thank you for reading!

Cassini Spacecraft: Top Discoveries

Our Cassini spacecraft has been exploring Saturn, its stunning rings and its strange and beautiful moons for more than a decade.

Having expended almost every bit of the rocket propellant it carried to Saturn, operators are deliberately plunging Cassini into the planet to ensure Saturn’s moons will remain pristine for future exploration – in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.

Let’s take a look back at some of Cassini’s top discoveries:

Titan

Under its shroud of haze, Saturn’s planet-sized moon Titan hides dunes, mountains of water ice and rivers and seas of liquid methane. Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet.

Both Earth and Titan have nitrogen-dominated atmospheres – over 95% nitrogen in Titan’s case. However, unlike Earth, Titan has very little oxygen; the rest of the atmosphere is mostly methane and traced amounts of other gases, including ethane.

There are three large seas, all located close to the moon’s north pole, surrounded by numerous smaller lakes in the northern hemisphere. Just one large lake has been found in the southern hemisphere.

Enceladus

The moon Enceladus conceals a global ocean of salty liquid water beneath its icy surface. Some of that water even shoots out into space, creating an immense plume!

For decades, scientists didn’t know why Enceladus was the brightest world in the solar system, or how it related to Saturn’s E ring. Cassini found that both the fresh coating on its surface, and icy material in the E ring originate from vents connected to a global subsurface saltwater ocean that might host hydrothermal vents.

With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.

Iapetus

Saturn’s two-toned moon Iapetus gets its odd coloring from reddish dust in its orbital path that is swept up and lands on the leading face of the moon.

The most unique, and perhaps most remarkable feature discovered on Iapetus in Cassini images is a topographic ridge that coincides almost exactly with the geographic equator. The physical origin of the ridge has yet to be explained…

It is not yet year whether the ridge is a mountain belt that has folded upward, or an extensional crack in the surface through which material from inside Iapetus erupted onto the surface and accumulated locally.

Saturn’s Rings

Saturn’s rings are made of countless particles of ice and dust, which Saturn’s moons push and tug, creating gaps and waves.

Scientists have never before studied the size, temperature, composition and distribution of Saturn’s rings from Saturn obit. Cassini has captured extraordinary ring-moon interactions, observed the lowest ring-temperature ever recorded at Saturn, discovered that the moon Enceladus is the source for Saturn’s E ring, and viewed the rings at equinox when sunlight strikes the rings edge-on, revealing never-before-seen ring features and details.

Cassini also studied features in Saturn’s rings called “spokes,” which can be longer than the diameter of Earth. Scientists think they’re made of thin icy particles that are lifted by an electrostatic charge and only last a few hours.

Auroras

The powerful magnetic field that permeates Saturn is strange because it lines up with the planet’s poles. But just like Earth’s field, it all creates shimmering auroras.

Auroras on Saturn occur in a process similar to Earth’s northern and southern lights. Particles from the solar wind are channeled by Saturn’s magnetic field toward the planet’s poles, where they interact with electrically charged gas (plasma) in the upper atmosphere and emit light.

Turbulent Atmosphere

Saturn’s turbulent atmosphere churns with immense storms and a striking, six-sided jet stream near its north pole.

Saturn’s north and south poles are also each beautifully (and violently) decorated by a colossal swirling storm. Cassini got an up-close look at the north polar storm and scientists found that the storm’s eye was about 50 times wider than an Earth hurricane’s eye.

Unlike the Earth hurricanes that are driven by warm ocean waters, Saturn’s polar vortexes aren’t actually hurricanes. They’re hurricane-like though, and even contain lightning. Cassini’s instruments have ‘heard’ lightning ever since entering Saturn orbit in 2004, in the form of radio waves. But it wasn’t until 2009 that Cassini’s cameras captured images of Saturnian lighting for the first time.

Cassini scientists assembled a short video of it, the first video of lightning discharging on a planet other than Earth.

Cassini’s adventure will end soon because it’s almost out of fuel. So to avoid possibly ever contaminating moons like Enceladus or Titan, on Sept. 15 it will intentionally dive into Saturn’s atmosphere.

The spacecraft is expected to lose radio contact with Earth within about one to two minutes after beginning its decent into Saturn’s upper atmosphere. But on the way down, before contact is lost, eight of Cassini’s 12 science instruments will be operating! More details on the spacecraft’s final decent can be found HERE.
