(TMU) — Waves are all around us. Everywhere we go we encounter them. From Texas to New York and from China to Canada, you’ll always have waves vibrating and creating part (even most) of your reality. We can find them in the form of sound, images, and even heat.
As Nikola Tesla once said:
“If you wish to understand the Universe think of energy, frequency, and vibration.”
And now, a team of scientists from the Moscow Institute of Physics and Technology and Russian corporation Neurobotics is understanding the universe inside our heads thanks to a device they created that is capable of “reading” the mind of the user. Science is always breaking the barrier between fiction and reality.
The team placed a cap of electrodes on the scalp of participants so they could record their brain waves (produced by synchronized electrical pulses from masses of neurons communicating with each other). This technique is noninvasive, with information gathered through an electrode-covered electroencephalography (EEG) headset.
They then had each participant watch 20 minutes worth of 10-second-long video fragments. The subject of each fragment fell into one of five categories and the researchers found they could tell which category of video a participant was watching just by looking at their EEG data.
In the researcher’s words:
“Here we hypothesize that observing the visual stimuli of different categories trigger distinct brain states that can be decoded from noninvasive EEG recordings. We introduce an effective closed-loop BCI system that reconstructs the observed or imagined stimuli images from the co-occurring brain wave parameters. The reconstructed images are presented to the subject as a visual feedback.”
To better understand the concept of brainwaves, let’s work with an analogy. We can think of brainwaves as musical notes, the low-frequency waves are like a deeply penetrating drum beat, while the higher frequency brainwaves are more like a subtle high pitched flute. Like a symphony, the higher and lower frequencies link and cohere with each other through harmonics.
We can understand this process as a transformation of waves to images.
“We did not expect that it contains sufficient information to even partially reconstruct an image observed by a person. Yet it turned out to be quite possible,” Grigory Rashkov, a junior researcher at MIPT and a programmer at Neurorobotics, said.
Of the method being noninvasive, Rashkov explained:
“Under present-day technology, the invasive neural interfaces envisioned by Elon Musk face the challenges of complex surgery and rapid deterioration due to natural processes—they oxidize and fail within several months.”
“We hope we can eventually design more affordable neural interfaces that do not require implantation,” Rashkov said.
As it turns out, the oil industry uses a similar method to find oilfields through processing frequencies that are sent to the subsurface of the earth to get an “image” of the layers of rock and fluids under our feet. That’s called Seismics.
It seems Tesla was right—we can understand the universe (even inside our heads) using frequency (and a touch of math, too).
Chinese Military Satellite Smashed by Russian Rocket in “Major Confirmed Orbital Collision”
In an incident that is likely illustrative of things to come, Chinese military satellite 1-02 was smashed after it appears to have collided into the debris from a disintegrating Russian rocket.
The collision, which occurred earlier this year, shows the increasing danger of space junk such as satellite parts and other miscellaneous jetsam littering the Earth’s orbit. An estimated 8,000 metric tons of space debris pose the risk of destroying functional equipment such as weather forecasting systems, telecoms and GPS systems – and even manned space travel missions – if the problem isn’t reined in.
The fate of the Chinese satellite was uncovered by Harvard astrophysicist and satellite tracker Jonathan McDowell.
The breakup of Yunhai 1-02 was initially reported by the U.S. Space Force’s 18th Space Control Squadron (18SPCS). However, it wasn’t until recently that McDowell found out what caused the breakup.
The astrophysicist soon found that it was destroyed by space junk that originated from a Russian Zenit-2 rocket that had launched a spy satellite in 1996. On Aug. 14, McDowell found a strange entry in a database on Space-Track.org: “Collided with satellite.”
“This is a new kind of comment entry — haven’t seen such a comment for any other satellites before,” McDowell tweeted.
“A quick analysis of the TLEs show that Yunhai 1-02 (44547) and [the debris object] passed within 1 km of each other (so within the uncertainty of the TLEs) at 0741 UTC Mar 18, exactly when 18SPCS reports Yunhai broke up,” he added, noting that this “looks to be the first major confirmed orbital collision in a decade.”
However, the Yunhai satellite still remains functional and is transmitting radio signals, notes Space.com.
The incident shows the growing likelihood of such collisions in the high-traffic, littered near-Earth orbital zone.
“Collisions are proportional to the square of the number of things in orbit,” McDowell explained. “That is to say, if you have 10 times as many satellites, you’re going to get 100 times as many collisions.”
He added: “So, as the traffic density goes up, collisions are going to go from being a minor constituent of the space junk problem to being the major constituent. That’s just math.”
A worst-case scenario of such collisions is known as the “Kessler Syndrome,” and describes the possibility of one collision setting in motion a chain of collisions. Such a disaster was the premise of the 2013 film “Gravity.”
One hopes that things don’t reach that point.
In the meantime, however, there have been a number of initiatives meant to tackle the growing problem of space debris, such as the ELSA-d spacecraft launched in a demonstration mission earlier this year.
Boston Dynamics Drops New Video Of 5-Foot Atlas Humanoid Robot Effortlessly Doing Parkour
Robot maker Boston Dynamics has released new video of its two-legged Atlas robot effortlessly completing a parkour obstacle course, offering a new display of its humanoid machines’ unsettling repertoire.
In the video, a pair of Atlas robots can be seen leaping over large gaps, vaulting beams, and even performing backflips. The robot can even be seen jumping over a board while using its arm to remain steady.
While the display seems like anything but “free” running – as the original developers of parkour had envisioned – the routine does seem like an impressive, if terrifying, display of effective coding that took months to perfect, according to the Hyundai-owned robotics firm.
“It’s not the robot just magically deciding to do parkour, it’s kind of a choreographed routine, much like a skateboard video or a parkour video,” said Atlas control lead Benjamin Stephens.
See for yourself:
Unlike its robotic dog Spot, which controversially hit New York City streets last year before being pulled, Atlas isn’t a production robot. Instead, it’s a research model meant to see how far the limits of robotics can be pushed.
In the past, Boston Dynamics has displayed the robot’s feats with videos of Atlas jogging and even busting out some cool dance moves.
Team lead Scott Kuindersma said in a statement that in about two decades, we can expect to coexist with robots that move “with grace, reliability, and work alongside humans to enrich our lives.”
Until then, some of us will continue to reserve our right to feel a bit queasy about the prospect of people being chased down by these skilled free-running (and dancing) machines.
South Korean Toilet Turns Poo Into Green Energy and Pays Its Users Digital Cash
What if your morning #2 not only powered your stove to cook your eggs, but also allowed you to pay for your coffee and pastry on the way to class?
It seems like an absurd question, but one university in South Korea has invented a toilet that allows human excrement to not only be used for clean power, but also dumps a bit of digital currency into your wallet that can be exchanged for some fruit or cup noodles at the campus canteen, reports Reuters.
The BeeVi toilet – short for Bee-Vision – was designed by urban and environmental engineering professor Cho Jae-weon of the Ulsan National Institute of Science and Technology (UNIST), and is meant to not only save resources but also reward students for their feces.
The toilet is designed to first deliver your excrement into a special underground tank, reducing water use, before microorganisms break the waste down into methane, a clean source of energy that can power the numerous appliances that dorm life requires.
“If we think out of the box, feces has precious value to make energy and manure,” Cho explained. “I have put this value into ecological circulation.”
The toilet can transform approximately a pound of solid human waste – roughly the average amount people poop per day – into some 50 liters of methane gas, said Cho. That’s about enough to generate half a kilowatt hour of electricity, enough to transport a student throughout campus for some of their school day.
Cho has even devised a special virtual currency for the BeeVi toilet called Ggool, or honey in Korean. Users of the toilet can expect to earn 10 Ggool per day, covering some of the many expenses students rack up on campus every day.
Students have given the new system glowing reviews, and don’t even mind discussing their bodily functions at lunchtime – even expressing their hopes to use their fecal credits to purchase books.
