Pink Poison, the Surprising New Trend That’s Saving Rhinos

Rhino experts discuss a bright approach to keeping poachers away.

1) Does not hurt rhinos

2) Discolours ivory (BRIGHT PINK) thus reducing saleability

3) Can be detected by airport scanners, even if ground up, thus increasing the chances you will be caught

4) Causes nausea, vomiting, and diarrhea if ingested by humans, thus driving away your customer base

Win. Win. Win. Win.

A photon checks into a hotel and is asked if he needs any help with his luggage. He says, “No, I’m traveling light.”

Your body is an incredibly bizarre machine.

“What you see is a myosin protein dragging an endorphin along a filament to the inner part of the brain’s parietal cortex which creates happiness. Happiness. You’re looking at happiness.”

Yes, sure its fun to see a lady spin around like that, but I had one of my friends ask me - “Where do you even use this mate?”

Here’s one application that I know very well off.

Spin Stabilization

If you have ever seen a rocket launch, you might know that sometimes the rockets are given a spin while launching. This is known as spin stabilization.

Basically, the rotational inertia of the rotating body will stabilize the rocket against any disturbances and help maintain its intended heading.

The same principle is used in rifling of firearms as well. **

YoYo DeSpin

Okay, now there is the question how to “De-spin” the rocket:

Well, you do what the lady does: stretch out your arms and you will slow down !

The rocket has weights connected to a cable that stretch out and almost immediately the rocket slows down. This maneuver is known as the YoYo DeSpin. ( Damn good name ! )

All thanks to the conservation of angular momentum !

Have a good one !

* Another method to stabilization : 3-axis stabilization

The origin of the universe was not by a singularity, since in a singularity, the laws of nature are not valid or do not exist,

some of my favourite absolutely SICK facts about the trappist-1 exoplanets: - theyre all very close to one another and to their star, so the length of a year on them varies from 1 to 20 DAYS - since they’re so close, the star appears a lot bigger than our sun from earth, and from one planet you could easily see the rest, some would even appear bigger than the moon from earth. you could literally see the surface of another planet with the naked eye!!! - they’re probably tidally locked to their star like our moon is locked to earth, meaning only one side of a planet ever faces the star, and on the other side it’s always night. the sun never sets or rises on any of the planets - the star is red, so the sunlight is red/orange, meaning if, for example, plants were to grow there, they could be black and that’s just what we know now, imagine how much cool stuff we have yet to discover about the trappist-1 system

Planets i learned about via youtube while procrastinating my english essay

Planet 55 Cancri e is basically a giant diamond. like the planet is a diamond. and it would be worth $26.9 nonillion

Planet Gliese 436 b is an ice planet that is constantly on fire do to its close proximity to its parent star. the ice doesn’t melt bc the planet’s gravity is so strong it physically prevents the ice from melting

Planet HD 189733b rains sideways glass…. constantly

Planet J1407-B has planetary rings that are 200x the size of saturn. if saturn’s ring were as big as J1407-B’s we’d be able to see them with our naked eye from earth AND they would dominate our sky and look larger than a full moon

Planet Wasp-12b rotates so close to its parent star that its slowly being consumed by the it

Planet Gliese 581c is one of the candidates for a planet that can support life however it orbits a tiny dwarf star and is tidally locked so one side is constantly subject to immense sunlight while the other is constantly in darkness. there’s a small area of the planet however, that is just the right temp to support life. u just can’t step out of said area. the skies are red and the plants would have be a black color instead of a green bc they would use infrared light for photosynthesis. (a message was actually sent to the planet in 2008 in hopes that there’s life on the planet but the message wont reach the planet until 2029).

Planet GJ 1214b is a water planet nicknamed “water world” is has no land at all and the water is so deep it goes down miles all the way to the planet’s core.

Planet Wasp-17b is the largest planet discovered thus far. its so large its existence contradicts our understanding of how planets are formed. and it has a retrograde orbit, so it orbits in the opposite direction of its parent star.

Planet HD 188753 has 3 suns you should have triple shadows and there would be almost daily eclipses. and no matter which direction u face on the planet u would always see a sunset

Planet HD106906b is the loneliest planet discovered thus far. its known as “super jupiter” bc its 11x bigger than jupiter. it orbits its parent star at a distance of 60 billion miles (which is v strange) hence why its the loneliest planet.

Planet Tres 2b is the darkest planet known. it reflects less than 1% of light (it reflects less light than coal and black acrylic paint). the tiny part of the planet that does reflect light is red making the planet glow a dim red.
