Two ways of dealing with tear gas grenades from comrades in Turkey: Either submerge them in water. Make sure you can close off the container cause the gas will still spread for a while. Or throw them in the fire so the gas burns off before it can spread.

Wow.

Robin Williams didn’t die from suicide. I only just heard the sad, sad news of Robin Williams’s death. My wife sent me a message to tell me he had died, and, when I asked her what he died from, she told me something that nobody in the news seems to be talking about.

When people die from cancer, their cause of death can be various horrible things – seizure, stroke, pneumonia – and when someone dies after battling cancer, and people ask ‘How did they die?’, you never hear anyone say ‘pulmonary embolism’, the answer is always ‘cancer’. A Pulmonary Embolism can be the final cause of death with some cancers, but when a friend of mine died from cancer, he died from cancer. That was it. And when I asked my wife what Robin Williams died from, she, very wisely, replied ‘depression’.

The word ‘suicide’ gives many people the impression that ‘it was his own decision,’ or ‘he chose to die, whereas most people with cancer fight to live.’ And, because depression is still such a misunderstood condition, you can hardly blame people for not really understanding. Just a quick search on Twitter will show how many people have little sympathy for those who commit suicide…

But, just as a Pulmonary Embolism is a fatal symptom of cancer, suicide is a fatal symptom of depression. Depression is an illness, not a choice of lifestyle. You can’t just ‘cheer up’ with depression, just as you can’t choose not to have cancer. When someone commits suicide as a result of depression, they die from depression – an illness that kills millions each year. It is hard to know exactly how many people actually die from depression each year because the figures and statistics only seem to show how many people die from ‘suicide’ each year (and you don’t necessarily have to suffer depression to commit suicide, it’s usually just implied). But considering that one person commits suicide every 14 minutes in the US alone, we clearly need to do more to battle this illness, and the stigmas that continue to surround it. Perhaps depression might lose some its ‘it was his own fault’ stigma, if we start focussing on the illness, rather than the symptom. Robin Williams didn’t die from suicide. He died from depression. It wasn’t his choice to suffer that.

  • You are never “not sick enough” to recover.
  • Recovery is hard, but it is worth it.
  • You have more strength than you could ever imagine.
  • You can get through this.

Brahmagupta, Indian mathematician (598 - 670), known as the “inventor of zero”. Picture from findinsideindia.com.
Brahmagupta was head of the astronomical observatory at Ujjain, a holy city in the Malwa region of central India. (Ujjain has been a center of learning since ancient times, and is known in Hindu tradition as the place where Krishna went to receive his education. The observatory of Ujjain was considered the prime meridian, as Greenwich England is today, making it the baseline for all astronomical observations.)From his observations he deduced that the moon is closer to the earth than the sun is, and that the earth and heavenly bodies are all spheres. His calculation of the length of the solar year is accurate to within about half an hour! But Brahmagupta is best known for his mathematical writings, and especially for developing the concept of zero as a number.In his great work Brahmasphutasiddhanta (“The Opening of the Universe”), Brahmagupta wrote:    When zero is added to a number or subtracted from a number, the number remains unchanged; and a number multiplied by zero becomes zero. Previous schoars had used various symbols as placeholders to show the lack of a number or digit. Brahmagupta was the first to treat zero as a number in its own right, something that could be used in calculations along with other numbers. In doing so, he extended the rules of arithmetic from the natural numbers to what we now call the integers, including zero and negative numbers. Here’s more rules from the Brahmasphutasiddhanta:    A debt minus zero is a debt.    A fortune minus zero is a fortune.    Zero minus zero is a zero.    A debt subtracted from zero is a fortune.    A fortune subtracted from zero is a debt.    The product of zero multiplied by a debt or fortune is zero.    The product of zero multipliedby zero is zero.    The product or quotient of two fortunes is one fortune.    The product or quotient of two debts is one fortune.    The product or quotient of a debt and a fortune is a debt.    The product or quotient of a fortune and a debt is a debt.(“Fortune” and “Debt” were Brahmagupta’s quite descriptive terms for what we’d now call positive and negative numbers.)This is one of those ideas that’s so simple that, from our vantage point centuries later, it’s hard to imagine anyone not understanding it, but people had been struggling along without zero for centuries. It must have taken a stroke of genius to realize that “nothing” is something!But he didn’t stop with negative numbers! The Brahmasphutasiddhanta also contains methods for:- Finding square roots, using an algorithm that Newton would rediscover centuries later!- Solving quadratic equations!- Trigonometry, including tables of sines and cosines!- Summing series of squares and cubes- Finding the area of cyclic quadrilateralsHis work holds up extremely well today. His approximation of Pi was correct to within a few hundredths. About the only place where modern mathematicians would disagree with Brahmagupta is his statement that 0 divided by 0 is 0, where today we leave division by zero undefined.Sources:http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Brahmagupta.htmlhttp://www.famous-mathematicians.com/brahmagupta/https://en.wikipedia.org/wiki/Brahmagupta

IMPORTANT

the second one? i can buy that somewhat. the first one? breasts are sexual organs.

I SWEAR TO FUCK. NO. NO THEY ARE NOT. BREASTS ARE MEANT TO FEED BABIES. BREASTS ARE NOT MEANT FOR SEXUAL FUCKING PLEASURE. BREASTS SOLE EVOLUTIONARY PURPOSE ARE TO FEED THE YOUNG, NOT TO HUMOUR MEN IN BED.

breasts are fucking secondary sex characteristics that have been oversexualized by assholes. by the logic of not allowing breasts to be shown, it should be illegal for people to have adam’s apples, beards, arm pit hair, etc. how about you actually know what you’re talking about before you open your ignorant mouth
