Cooper : You don't believe we went to the Moon?
Ms. Kelly : I believe it was a brilliant piece of propaganda, that the Soviets bankrupted themselves, pouring resources into rockets and other useless machines...
Cooper : Useless machines?
Ms. Kelly : And if we don't want to repeat of the excess and wastefulness of the 20th Century then we need to teach our kids about this planet, not tales of leaving it.
Cooper : You know, one of those useless machines they used to make was called an MRI, and if we had any of those left the doctors would have been able to find the cyst in my wife's brain, *before* she died instead of after, and then she would've been the one sitting here, listening to this instead of me, which would've been a good thing because she was always the... calmer one.

The human brain
The brain is the control center of our body. It is located inside the skull and floats in a liquid called cerebrospinal fluid. Its shape resembles a large walnut. It communicates with the rest of the body through “wires” called nerves and through hormones. Neural signals can travel at speeds of up to 428 km/h.
The brain is roughly the size of two fists and weighs between 1,250 and 1,600 grams. Heavier individuals tend to have heavier brains. Men’s brains are heavier than women’s, but the weight of the brain has no connection to intelligence. About 60% of the brain consists of fatty acids.
The brain is divided into three parts: the cerebellum, the brainstem, and the cerebral cortex.
• The cerebellum is responsible for balance, movement, and coordination.
• The brainstem controls digestion and ensures that the heart and breathing do not stop.
• The cerebral cortex is the outer layer that consists of neurons, which you can read about below in our website (issue 4 of the magazine)

PINning down future problems
Study finds hackers could use brainwaves to steal passwords
Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user’s passwords by monitoring their brainwaves.
EEG headsets are advertised as allowing users to use only their brains to control robotic toys and video games specifically developed to be played with an EEG headset. There are only a handful on the market, and they range in price from $150 to $800.
Nitesh Saxena, Ph.D., associate professor in the UAB College of Arts and Sciences Department of Computer and Information Sciences, and Ph.D. student Ajaya Neupane and former master’s student Md Lutfor Rahman, found that a person who paused a video game and logged into a bank account while wearing an EEG headset was at risk for having their passwords or other sensitive data stolen by a malicious software program.
“These emerging devices open immense opportunities for everyday users,” Saxena said. “However, they could also raise significant security and privacy threats as companies work to develop even more advanced brain-computer interface technology.”
Saxena and his team used one EEG headset currently available to consumers online and one clinical-grade headset used for scientific research to demonstrate how easily a malicious software program could passively eavesdrop on a user’s brainwaves. While typing, a user’s inputs correspond with their visual processing, as well as hand, eye and head muscle movements. All these movements are captured by EEG headsets. The team asked 12 people to type a series of randomly generated PINs and passwords into a text box as if they were logging into an online account while wearing an EEG headset, in order for the software to train itself on the user’s typing and the corresponding brainwave.
“In a real-world attack, a hacker could facilitate the training step required for the malicious program to be most accurate, by requesting that the user enter a predefined set of numbers in order to restart the game after pausing it to take a break, similar to the way CAPTCHA is used to verify users when logging onto websites,” Saxena said.
The team found that, after a user entered 200 characters, algorithms within the malicious software program could make educated guesses about new characters the user entered by monitoring the EEG data recorded. The algorithm was able to shorten the odds of a hacker’s guessing a four-digit numerical PIN from one in 10,000 to one in 20 and increased the chance of guessing a six-letter password from about 500,000 to roughly one in 500.
EEG has been used in the medical field for more than half a century as a noninvasive method for recording electrical activity in the brain. Electrodes are placed on the surface of the scalp to detect brain waves. An EEG machine then amplifies the signals and records them in a wave pattern on graph paper or a computer. EEG can be combined with a brain-computer interface to allow a person to control external devices. This technology was once highly expensive and used mostly for scientific research, like the production of neuroprosthetic applications to help disabled patients control prosthetic limbs by thinking about the movements. However, it is now being marketed to consumers in the form of a wireless headset and is becoming popular in the gaming and entertainment industries.
“Given the growing popularity of EEG headsets and the variety of ways in which they could be used, it is inevitable that they will become part of our daily lives, including while using other devices,” Saxena said. “It is important to analyze the potential security and privacy risks associated with this emerging technology to raise users’ awareness of the risks and develop viable solutions to malicious attacks.”
One potential solution proposed by Saxena and his team is the insertion of noise anytime a user types a password or PIN while wearing an EEG headset.
Find
Want to find, a heart in brine. As irregular as it goes, but finds symmetry in mine.
Want to find, a brain in pieces , a piece for love and a piece of wise, and takes on them in beautiful leases
Want to find , a hand in action, of kindness to the world yet wanting just a fraction.
7 billion people on this land of god, walking here and there, fully absorbed in ignorance and rush, and I wonder if I'll meet a soul ,for whom my soul is lobbed.. (21.11.19)

I hear you,
I can feel you
I can’t see you.
Sickness
Weakness
You make me do all these things.
Love
Hate
Twisted emotions
You control all these .
My movement
My touch
My taste
Are all crazy things
It scares me
To know your the most powerful thing.

As I drove into work mostly still asleep, I had a sudden, horrifying sensation I left my light saber at home. The awake half of my brain took a minute to process how ridiculous the notion was I: Have a real light saber; would need said light saber for work. Sleeping only two-three hours a night is not a good way to live.
