sorry but as a STEM major you write almost as much as humanities majors do. lab reports can range from 20-35 handwritten pages for a big experiment, and clear, unambiguous language is vital for gaining full points for every assignment. daily textbook readings can take hours. on top of all of this we must master math that makes your head spin, intricate chemical reactions, and unintuitive physics phenomena. stop whining.

literally the only thing i ever “whined” about was stem majors acting exactly like you are right now. I know that y’all have a lot going on (including writing), but so do we. 

College is hard for everyone, no matter your major. There’s no need to be elitist about it, so please take your attitude elsewhere thanks!!

hMMM (gosh, I’ve never thought of this)

The main difference between Pokemon and other living beings (i.e. plants and humans) is that they are essentially “high energy”. Think electrons: always jumping around, creating bursts of energy, and searching for balance. This makes Pokemon fairly unstable, and like unstable atoms, they are super reactive to stimulus and susceptible to changing bodily structure. 

Some Pokemon evolve via level up because their current body can’t contain the amount of energy they’ve acquired, so they change form to accommodate. Others evolve when in contact with an item, akin to how chemical reactions reactions work. Final evolution = physical stability. 

Evolution via trading occurs differently than via item because the Pokemon’s body is in a completely non-physical state while being transferred, allowing its atoms to react separate/individually. This is a whole new form of stimuli only made recently available to Pokemon.

However, there are rare cases where this can occur in the wild. Sometimes when a Pokemon enters a low energy state (fainted or close to), its body will partially disintegrate, creating a similar situation to evolution or trading, and in order to pull its body back together it will have to evolve. If it evolves via trade AND item, it will need to be in contact with the item during this phenomenon.


I’ve spent the past few months attempting to figure out a framework for Ghost Physics in the Danny Phantom universe? Enjoy my crazed scribblings.

Cliff notes version: The Ghost Zone is our dimension’s 4D “atmosphere,” absorbing harmful trans-dimensional radiation. Ghosts are made of the Ghost Zone’s version of matter, called ectoplasm, a substance capable of 4D motion (video explanation of that), “toggling” how physical forces (esp. electromagnetism and gravity) interact with it, and storing huge amounts of energy. A ghost’s unique nervous system and encoded body plan (the ecto-signature) remains in the upper energy levels of the Ghost Zone at all times, remotely controlling their body. Danny can chemically change his body between ectoplasm and regular matter, and has both a normal physical brain and an ecto-signature.

Humanity is so beautiful

So I learned two cool things about humans: 
Humans have stripes!
Human skin is overlaid with what dermatologists call Blaschko’s Lines, a pattern of stripes covering the body from head to toe. The stripes run up and down your arms and legs and hug your torso. You cannot see them without special equipment as the difference between the stripe cells and the non-stripes are too subtle for human eyes to pick up. You will also notice them at if something irritates the skin, as rashes and moles can form along these invisible lines.

Humans are bio-luminescent!
We glow in the dark. Natural chemical reactions in our cells let out some energy in the form of visible light. Unfortunately this light is very weak, about 1000 times weaker than the eye can see. Scientists still don’t know if there are animals capable of seeing this light in humans. 

So, it gave me an idea, and I will be writing something on it, but I’m also eager to see where others would go with the idea: what if humans met a race that could see our stripes, or our glow, or both! 
My take on the idea will involve the aliens adoring these glowing stripy creatures. Humans, meanwhile, are really confused about why these aliens find us so much more attractive than the more colourful creatures out there. Their compliments would confuse us. We literally cannot see what makes us beautiful to them. 

Anyone who wants to write this, feel free to go other places; love, hate, disgust, confusion. Any reaction from the humans, or aliens, can make a good story. 

1,000 Days in Orbit: MAVEN’s Top 10 Discoveries at Mars

On June 17, our MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet.

Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

Here’s a countdown of the top 10 discoveries from the mission so far:

10. Unprecedented Ultraviolet View of Mars

Revealing dynamic, previously invisible behavior, MAVEN was able to show the ultraviolet glow from the Martian atmosphere in unprecedented detail. Nightside images showed ultraviolet “nightglow” emission from nitric oxide. Nightglow is a common planetary phenomenon in which the sky faintly glows even in the complete absence of eternal light.

9. Key Features on the Loss of Atmosphere

Some particles from the solar wind are able to penetrate unexpectedly deep into the upper atmosphere, rather than being diverted around the planet by the Martian ionosphere. This penetration is allowed by chemical reactions in the ionosphere that turn the charged particles of the solar wind into neutral atoms that are then able to penetrate deeply.

8. Metal Ions

MAVEN made the first direct observations of a layer of metal ions in the Martian ionosphere, resulting from incoming interplanetary dust hitting the atmosphere. This layer is always present, but was enhanced dramatically by the close passage to Mars of Comet Siding Spring in October 2014.

7. Two New Types of Aurora

MAVEN has identified two new types of aurora, termed “diffuse” and “proton” aurora. Unlike how we think of most aurorae on Earth, these aurorae are unrelated to either a global or local magnetic field.

6. Cause of the Aurorae

These aurorae are caused by an influx of particles from the sun ejected by different types of solar storms. When particles from these storms hit the Martian atmosphere, they can also increase the rate of loss of gas to space, by a factor of ten or more.

5. Complex Interactions with Solar Wind

The interactions between the solar wind and the planet are unexpectedly complex. This results due to the lack of an intrinsic Martian magnetic field and the occurrence of small regions of magnetized crust that can affect the incoming solar wind on local and regional scales. The magnetosphere that results from the interactions varies on short timescales and is remarkably “lumpy” as a result.

4. Seasonal Hydrogen

After investigating the upper atmosphere of the Red Planet for a full Martian year, MAVEN determined that the escaping water does not always go gently into space. The spacecraft observed the full seasonal variation of hydrogen in the upper atmosphere, confirming that it varies by a factor of 10 throughout the year. The escape rate peaked when Mars was at its closest point to the sun and dropped off when the planet was farthest from the sun.

3. Gas Lost to Space

MAVEN has used measurements of the isotopes in the upper atmosphere (atoms of the same composition but having different mass) to determine how much gas has been lost through time. These measurements suggest that 2/3 or more of the gas has been lost to space.

2. Speed of Solar Wind Stripping Martian Atmosphere

MAVEN has measured the rate at which the sun and the solar wind are stripping gas from the top of the atmosphere to space today, along with details of the removal process. Extrapolation of the loss rates into the ancient past – when the solar ultraviolet light and the solar wind were more intense – indicates that large amounts of gas have been lost to space through time.

1. Martian Atmosphere Lost to Space

The Mars atmosphere has been stripped away by the sun and the solar wind over time, changing the climate from a warmer and wetter environment early in history to the cold, dry climate that we see today.

Maven will continue its observations and is now observing a second Martian year, looking at the ways that the seasonal cycles and the solar cycle affect the system.

Chemical reactions as art

Because space is vast and full of mysteries, NASA is developing a new rocket, a new spacecraft for astronauts and new facilities to launch them from. Our Space Launch System will be unlike any other rocket when it takes flight. It will be bigger, bolder and take astronauts and cargo farther than humankind has ever been – to deep space destinations like the moon, a deep space gateway or even Mars. 

The Gravity-Slayer

When you plan to get to space, you use ice and fire. NASA’s Space Launch System uses four rocket engines in the center of the rocket and a pair of solid rocket boosters on opposite sides. All this power will propel the Space Launch System to gravity-slaying speeds of more than 17,000 miles per hour! These are the things we do for space exploration, the greatest adventure that ever was or will be.

It is Known

It is known that according to Newton’s third law, for every action there is an equal and opposite reaction. That’s how rocket propulsion works. Fuel burned in combustion chambers causes hot gases to shoot out the bottom of the engine nozzles. This propels the rocket upward. 


It is also known that when you combine hydrogen and oxygen you get: water. To help SLS get to space, the rocket’s four RS-25 engines shoot hydrogen and oxygen together at high speeds, making billowing clouds of steaming hot water vapor. The steam, funneled through the engine nozzles, expands with tremendous force and helps lift the rocket from the launchpad. 

RS-25: Ice King

It takes a lot of fuel (hydrogen) and a lot of oxygen to make a chemical reaction powerful enough to propel a rocket the size of a skyscraper off the launch pad. To fit more hydrogen and oxygen into the tanks in the center of the rocket where they’re stored, the hydrogen and oxygen are chilled to as low as -400 degrees Fahrenheit. At those temperatures, the gases become icy liquids. 

The Fire that Burns Against the Cold

The hydrogen-oxygen reaction inside the nozzles can reach temperatures up to 6,000 degrees Fahrenheit (alas, only Valyrian steel could withstand those temperatures)! To protect the nozzle from this heat, the icy hydrogen is pumped through more than a thousand small pipes on the outside of the nozzle to cool it. After the icy liquid protects the metal nozzles, it becomes fuel for the engines. 

Where is my FIRE?

The Space Launch System solid rocket boosters are the fire and the breakers of gravity’s chains. The solid rocket boosters’ fiery flight lasts for two minutes. They burn solid fuel that’s a potent mixture of chemicals the consistency of a rubber eraser. When the boosters light, hot gases and fire are unleashed at speeds up to three times the speed of sound, propelling the vehicle to gravity-slaying speed in seconds. 

Testing is Here

To make sure everything works on a rocket this big, it takes a lot of testing before the first flight. Rocket hardware is rolling off production lines all over the United States and being shipped to testing locations nationwide. Some of that test hardware includes replicas of the giant tanks that will hold the icy hydrogen and oxygen.

As Rare as Dragonglass

Other tests include firing the motor for the solid rocket boosters. The five-segment motor is the largest ever made for spaceflight and the part that contains the propellant that burns for two fiery, spectacular minutes. It’s common during ground test firings for the fiery exhaust to turn the sand in the Utah desert to glass.

Hold the Door

When all the hardware, software and avionics for SLS are ready, they will be shipped to Kennedy Space Center where the parts will be assembled to make the biggest rocket since the Saturn V. Then, technicians will stack Orion, NASA’s new spacecraft for taking astronauts to deep space, on top of SLS. All this work to assemble America’s new heavy-lift rocket and spacecraft will be done in the Vehicle Assembly Building – one of the largest buildings in the world. Hold the door to the Vehicle Assembly Building open, because SLS and Orion are coming!
