Since it’s Super Bowl Sunday and none of the teams I care about are playing this year (Mark Sanchez is a disgrace), I figure I’ll root for the Ravens because at least that’s a dinosaur.
 Anyway, the common raven (Corvus corax) is a very intelligent bird related to crows and blue jays. Capable of problem solving, ravens have been recently discovered to use gestures, like pointing, in the wild. Ravens interact with each other using their beaks, usually at the opposite sex, pointing at objects of interest. This is the first time this behavior has been observed in the wild by a non-primate species.

Is Pink a Color? 

MinutePhysics, a popular YouTube channel, posted a video a little while back saying that there is no pink light. This seems to have sparked a debate over whether or not pink is a color - an issue not really brought up by the original video. So, is pink a color? As usual, science is more complicated than you’d initially believe.

Since this is a physics blog, let’s go with the usual physical understanding of what ‘color’ is. Every color, effectively, is just a certain frequency of light. Electromagnetic radiation is characterized by its wavelength, frequency, intensity, etc. When the wavelength is within the visible spectrum (the range of wavelengths humans can visually perceive, approximately from 390 nm to 700 nm), it is known as “visible light,” a range which we breakdown as Roy G. Biv. 

There is no single frequency which our brains correspond to “pink” light. Then, how does pink exist? Effectively, pink is a combination of red and violet light - two colors from opposite sides of the visible spectrum. Since these two colors are literal opposites on the visible spectrum, pink could not exist as a fundamental frequency in nature (if you tried to average out the frequencies and “mix” them, you’d arrive at a color somewhere near the middle of the spectrum, around yellow or green). Thus, pink isn’t a fundamental frequency floating out there in space - a single frequency that we could call “pink” doesn’t exist. 

Hold on Tumblr bro, Pink obviously exists, I see it on Nicki Minaj all the time! 

Yes, yes - what we perceive as Pink does exist on its own, but does that necessarily make it a true color? Will Pink be excluded from the highly exclusive Color Club much like Pluto was ousted from the Planetary Patrol?

Take a second to look around you, you’ll see tons of objects - probably many colored ones. When you look at, for example, a red object - that object absorbs all of the other frequencies except red, and it reflects red back to you. However, when you look at a pink object - you are not seeing pink wavelengths of light. An object would appear pink because wavelengths of both red and violet are being reflected - and our brains perceive it as a new “color,” namely pink.

On a very fundamental level, pink is not a fundamental part of the universe - because no color is. The universe is chock full of electromagnetic radiation, and the only truly fundamental properties of it are wavelength, amplitude, frequency, etc. Color is a phenomenon completely produced by your brain - it’s how we perceive the light. Even different animals perceive light differently than us - like certain animals that can see beyond the visible spectrum, including infrared light. As biologist Timothy H. Goldsmith wrote for Scientific American, “color is not actually a property of light or of objects that reflect light, it is a sensation that arises within the brain.” So, by existing only as a human means of understanding the universe, pink is just as “real” as any other color. 

So, there you have it - pink is not a part of the light spectrum, it is the effect of our brains filling the gap between blue and violet, but does that make it any less of a color than anything else? 

Let’s look at two common definition for what a color is - one artistic and one scientific. 

Scientific Definition: The sensation produced by the effect of light waves striking the retina of the eye. The color of something depends mainly on which wavelengths of light it emits, reflects, or transmits.

Artistic Definition: Color is the element of art that is produced when light, striking an object, is reflected back to the eye.

While there is no fundamental definition of color in all respects, personally, I’d say that pink fits both of these descriptions. Since no color is a fundamental property of the universe, pink does not exist as a part of the visible spectrum, but since all colors are just fabrications of our brain, I have to side with pink here. There are intelligent people on both sides of this debate, and one’s interpretation of definition seems to be how one decides whether to draw the line or not to exclude pink. Where do you stand?

Today a psychologist said something to me. He said that the majority of people live within a box, and that’s their entire reality. All they see is the inside of the box, and they’re ‘asleep’ to anything else. People that have suffered from some form of mental illness are ‘awake’ because they’ve seen reality outside the box. He said no matter how hard people try to put the person back into the box, they will never fit, because they’ve seen something beyond it all.

The Most Gorgeous Book Ever Has No Words Or Pictures, Just Color

This is the RGB Colorspace Atlas by Tauba Auerbach. The 8”x8” hardcover tome is pretty much an encyclopedia of every color in the RGB index. It’s huge, it’s gorgeous, and I want one.

I KNOW WHAT THIS NEEDS

It’s like they were made for each other.

i swear to fucking hell if you fuckers start shipping a book and i pen i will forcibly shove you back into the pits of hell you came from

Sensors alight, the pen trailed itself sensually down the gradient shift from yellow to blue along ample curve of paper, dipping closer and closer to the book’s spine.

“Can you imagine it?” the pen whispered, whirring and selecting #00563F with practiced intimacy. “Just picture it. With your collection and my potential…we can color the world.”

“The Freshest Kids: A History Of The B-Boy” (2002)


Old school bboys talking about the birth, early years, and evolution of bboying culture up to 2000. A great intro into breaking culture documentary I would suggest if you have the slightest interest in bboying.

This is Venus, a 3 year old chimera cat.

Chimera cat is one individual organism, but genetically its own fraternal twin. A chimera is typically formed from four parent cells (either two fertilized eggs, or two early embryos that have fused together). When the organism forms, the cells that had already begun to develop in the separate embryos keep their original phenotypes and appearances. This means that the resulting animal is a mixture of tissues and can look like this gorgeous (but bizarre) kitty.



apparently this probably isn’t due to true chimerism but i don’t even care because it sounds awesome

ooh i must use that rubber band trick.

:o Nice! I’m sure I’ll use a good portion of these sometime.

AmoeBAND became a 2012 IDEA Award Finalist by innovating every possible aspect of the plaster (band aid).

The design revisions were:  

- Strategic cut-outs shape to fit fingers in such a way that it is easy to bend them and not disrupt the bandage.

- An intelligent dressing material allows you to regularly check wounds from the outside, without upsetting the healing process.“According to research, the when an infection of a wound is detected, the pH value is between 6.5 and 8.5. AmoeBAND’s indicator cross turns purple, alerting the user needs to change it immediately.

- Since the bandage material used exudes a leather-like feel, availability in different skin-tones helps it blend in, without overly highlighting the injury.

- The packaging has been redesigned to a matchbox style and includes Braille instructions.

Hat tip to designers Tay Pek-Khai, Hsu Hao-Ming, Tsai Cheng-Yu, Chen Kuei-Yuan, Chen Yi-Ting, Lai Jen-Hao, Ho Chia-Ying, Chen Ying-shan, Weng Yu-Ching and Chung Kuo-Ting

They have different skin tones, too. OHMYGOD
I fucking love these!

FOR AUSTRALIAN RESIDENTS.


Give the above number (0450 352 004) out to men or anyone who doggedly persists in trying to get your number even after you’ve already said no.

SAVE THIS NUMBER IN YOUR PHONE FOR EASY RECALL! 

We have all had the experience of enjoying ourselves whilst out, minding our own business, when a strange man will bail us up with unscolicited attention in the effort to convince us to go out with him. These men will not take no for an answer, but will hound us with “kindness”, attempting to wear us down through the sheer force of their persistence even though we communicate a lack of interest. Such men will often become resentful and indignant when spurred because they believe themselves to be “nice guys” just trying to show us appreciation, despite the fact they cannot respect our boundaries and our wishes. They behave as though they are entitled to our attention and we owe them our time just because they decided they thought we were beautiful.

Often times, this degree of unwanted attention becomes a type of passive bullying, leaving us feeling unsafe, insecure and uncomfortable without any sure ways of getting out of the situation because the man in question is trying to set it up so the only exit is giving in. Women are groomed to be nice and pleasant always in social interactions and because these guys don’t use any obvious nastiness it leaves us more conflicted about being assertive.

DON’T PUT UP WITH IT ANY LONGER!

GIVE THESE DISRESPECTFUL MEN THIS NUMBER:

0450 352 004

WHEN THEY CALL IT, THEY WILL HEAR THE FOLLOWING MESSAGE:

Hello. If you have been given this number, it means that you have made someone feel uncomfortable, unsafe, perhaps even threatened. Most likely you have pestered a woman for her phone number, even after she said no. Maybe even said no repeatedly. You put so much pressure on this woman she had no choice but to give you this number in order to get you to leave her alone. If you want to have more success with women in the future, learn to respect our boundaries and our autonomy and accept that we don’t owe you attention. No means no, even when you’re not about to stick your dick in someone. If you would like to learn how to be more respectful towards women, please visit ialreadysaidno.tumblr.com

SAVE THIS NUMBER IN YOUR PHONE FOR EASY RECALL! 

PLEASE REBLOG THIS AND SPREAD THIS AROUND!

Excellent idea and legit too! Just called it and the voice on the end is fantastically perky and snarky.

Australians! Save it, memorise it, use it. I know I will.

Wow. This is awesome. Can we haz 1 for U.S?

Internet rumors have prompted new research into the origins of the Statue of Liberty, American’s 151-foot-tall monument to freedom erected in New York Harbor in 1886.

The traditional view, as taught to American schoolchildren for the past hundred years, holds that Lady Liberty was created to commemorate the friendship forged between the United States and France during the Revolutionary War. By 1903, when the statue was inscribed with Emma Lazarus’s poetic words, “Give me your tired, your poor, Your huddled masses yearning to breathe free,” it had come to symbolize America’s status as a safe haven for refugees and immigrants from every corner of the world.

The rumors, which have circulated in various forms and served as the direct inspiration for National Park Service anthropologist Rebecca Joseph’s decision to revisit the Statue of Liberty’s past, tell quite a different story:

A History Lesson
It is hard to believe that after my many years of schooling secondary and post) the following facts about the Statue of Liberty was never taught. Hundreds of thousands if not millions of people including myself have visited the Statue of Liberty over the years but yet I’m unable to find one person who knows the true history behind the Statue- amazing. Yes,amazing that so much important Black history (such as this) is hidden from us (Black and White). What makes this even worse is the fact that the current twist on history perpetuates and promotes white supremacy at the expense of Black Pride.

During my visit to France I saw the original Statue of Liberty. However there was a difference, the statue in France is Black. The Statue of Liberty was originally a Black woman, but, as memory serves, it was because the model was Black.

In a book called “The Journey of The Songhai People”, according to Dr. Jim Haskins, a member of the National Education Advisory Committee of the Liberty-Ellis Island Committee,professor of English at the University of Florida, and prolific Black author, points out that what stimulated the original idea for that 151 foot statue in the harbor.

He says that what stimulated the idea for the creation of the statue initially was the part that Black soldiers played in the ending of Black African Bondage in the United States. It was created in the mind of the French historian Edourd de Laboulaye, chairman of the French Anti-Slavery Society, who, together with sculptor Frederic Auguste Bartholdi,proposed to the French government that the people of France present to the people of the United States through the American Abolitionist Society, the gift of a Statue of Liberty in recognition of the fact that Black soldiers won the Civil War in the United States.

It was widely known then that it was Black soldiers who played the pivotal role in winning the war, and this gift would be a tribute to their prowess. Suzanne Nakasian, director of the Statue of Liberty, Ellis Island Foundations’ National Ethnic Campaign said that the Black Americans’ direct connection to Lady Liberty is unknown to the majority of Americans,BLACK or WHITE.

When the statue was presented to the U.S. Minister to France in 1884, it is said that he remonstrated that the dominant view of the broken hackles would be offensive to a U.S. South, because since the statue was a reminder of Blacks winning their freedom. It was a reminder to a beaten South of the ones who caused their defeat, their despised former captives.

Documents of Proof:

1.) You may go and see the original model of the Statue of Liberty, with the broken chains at her feet and in her left hand. Go to the Museum of the City of NY, Fifth Avenue and 103rd Street write to Peter Simmons and he can send you some documentation.

2.) Check with the N.Y. Times magazine, part II_May 18, 1986. Read the article by Laboulaye.

3.) The dark original face of the Statue of Liberty can be seen in the N.Y. Post, June 17, 1986, also the Post stated the reason for the broken chains at her feet.

4.) Finally, you may check with the French Mission or the French Embassy at the U.N. or in Washington, D.C. and ask for some original French material on the Statue of Liberty, including the Bartholdi original model.

You can call in September (202) 944-6060 or 6400. Please pass this information along!

Oh my god! Im not American but this shocks me. How can this not be known? & why does it not have many reblogs?

Happy 4th of July, errybody.

I’ve already reblogged a story about this a while back, but I’m doing it again because HAPPY 4TH ENJOY YOU SOME MORE EDUCASHUNS

The first independent millionaire in the United States is a rags to riches story of an African-American woman by the name of Madame C.J. Walker. Born to former slaves, on a plantation in Delta, Louisiana, Walker was orphaned at a young age. In the 1890’s Walker lost most of her hair due to a scalp ailment, but this coupled with working at her brother’s barber shop, would lead to a successful beauty supply empire that lives on to this day.

This is particularly interesting because not only was she the first independent millionaire, she was also a woman of color.


She has other accomplishments besides being a beauty entrepreneur: she also helped save Frederick Douglass’ home from destruction and campaigned to make lynching a federal crime.

She dedicated her whole life to the advancement of people of color, even hosting many race-related meetings in her own home.
