Don’t waste your time with explanations: people only hear what they want to hear.

Paulo Coelho (via z-philosophy)

Now that we’ve left behind the philosophy of religion, it’s time to start exploring what other ways might exist to find meaning in the world. Today we explore essentialism and its response: existentialism. We’ll also learn about Jean-Paul Sartre and his ideas about how to find meaning in a meaningless world.

How the power of imagination can shape and redefine society

The key is to recognize that our imaginings must be in some way tethered to the world in order for them to be useful to us. When we let our imagination fly completely free, it can be of use to us, but only in the transcendent sense. 

The power of imagination is not to be underestimated. As Albert Einstein accredited a plethora of his pioneering scientific work to his imagination, Martin Luther King’s dream allowed him to convey his idea of a better, more tolerable society. These changes are made possible when the imagination drifts into an alternate space, considering the world as it is currently in its entirety, while dreaming of an improved version of it.

Some of the heaviest elements ever seen have been given tentative names by their discoverers. The namesakes? Three places and a Russian dude.

These names aren’t settled on quite yet - there is a five month probation period during which the International Union of Pure and Applied Chemistry (IUPAC) welcomes public comment. You can email the IUPAC president directly with your thoughts.

If you discovered an element, what would you name it?

PBS NewsHour has a new science video series called ScienceScope - and their first episode is all about smells!

Scientists, sponsored by the National Science Foundation and the White House Brain Initiative, are trying to understand how smells travel, and how we detect them. They simulate the turbulent wafting of an order with dye in water. The hope is that this research will lead to smell-detecting robots that could replace search dogs.

A team of scientists has developed “robot flies” about the size of a quarter that can perch on almost any surface.

The perching works using static electricity. Each drone carries a tiny copper electrode on its head. When the electrode is energized, it creates a static charge that sticks the robot to a surface. Turning off the electrode sends the little drone back into the air.

Perching is important because it makes the robots more energy efficient. Perching is up to a thousand times more energy-efficient than hovering in place, the researchers say.

The luminous haze that obscures our view of the constellations - light pollution -is one of the most prevalent forms of environmental alteration. Its impact is felt across a swath of life from the migration of sea turtles to the circadian rhythm of humans. 

A new atlas of light pollution created by an international team of scientists reveals just how pervasive this artificial glow is. The atlas shows that more than 80% of the world and more than 99% of the U.S. and European populations live under light-polluted skies. The Milky Way is hidden from more than one-third of humanity, including 60% of Europeans and nearly 80% of North Americans.

How Churchill engineered the holocaust of 3 million Indians

As the resistance swelled, Churchill announced: “I hate Indians. They are a beastly people with a beastly religion.” This hatred killed. To give just one, major, example, in 1943 a famine broke out in Bengal, caused – as the Nobel Prize-winning economist Amartya Sen has proved – by the imperial policies of the British. Up to 3 million people starved to death while British officials begged Churchill to direct food supplies to the region. He bluntly refused. He raged that it was their own fault for “breeding like rabbits”. At other times, he said the plague was “merrily” culling the population.  Skeletal, half-dead people were streaming into the cities and dying on the streets, but Churchill – to the astonishment of his staff – had only jeers for them. “If food is so scarce, why hasn’t Gandhi died yet?”

Things brown/south asian tumblr will probably never address:

Antiblackness that actually involves the input of black south asians & black people in general

Ignoring the fact that South Asia is comprised of 8 countries: Afghanistan, Pakistan, Bangladesh, Nepal, Bhutan, India, Maldives, and Sri Lanka.

Lack or complete ignorance of north east indian culture and peoples.

Cultural hegemony India tends to have over representing South Asia

Discussion of caste which doesn’t reduce it down to an old practice that doesn’t actively shape an individual’s life in a variety of ways that are not exclusive to socioeconomic struggles.

How the discussion of the South Asian diaspora focuses mainly on those living in the West.

Hindutva

Steve McCurry making a name for himself off of the exploitation and exotification of South Asian faces and bodies (see: Sharbat Gula: known globally merely as “The Afghan Girl”

Ignorance of the issues Adivasi peoples face across South Asia.

Exploitation of the bodies of South Asian women for surrogacy by Westerners.

Savarna appropriation of Avarna arts redeeming it anew with culture now that it’s been mutilated by forward castes. (ie: Appropriation of Sadir into modern day Bharatnatyam)

The creation of good and bad brown/south asian dichotomy in the West Post 9/11 (ie: Indian peoples are characterized/seen as intelligent spiritual peaceful people while Pakistani and Afghani peoples are characterized/seen as violent terrorists or oppressed women who are labeled under islamophobic terms such as “radical muslim”

The lack of discussion about the South Asian diaspora in the Caribbean and South America.

Discrimination against Black African students living in South Asia.

Portrayal of Hinduism & Buddhism as peaceful religions while Islam is portrayed as violent and backwards.

Complete ignorance or writing off of Southern & Northeast Indian cultures by North Indians and Northern South Asians alike as not being authentically Indian or only discussing it when talking about the different regions of India.

Shadeism

How Bollywood has stolen, appropriated, and made racist caricatures of Indians and Non-Indians who are not Savarna North Indians. (See: Chennai Express, blackface meant to represent native Hawaiian peoples seen in the Hawa Hawai song in Mr. India, Shekhar Kapur’s Bandit Queen, etc)

Misogyny and sexual violence against Dalit women.

Erasure of brown skin in South Asian media, replacing brown skinned South Asian women with extremely light skinned South Asian or white women calling them the ideal faces of South Asian womanhood and beauty.
