Cat’s eye camera can detect nuclear core radiation
Scientists at the University of Lancaster, England have created a special “cat’s eye” camera capable of seeing radiation emitted by a nuclear reactor. This camera has a nuclear detector that can “see” the high intensity fast-neutrons and gamma rays simultaneously and can monitor the fuel burn-up in the nuclear power plant.
Research student Jonathan Beaumont and Malcolm Joyce, professor of nuclear engineering developed the camera by being inspired by the eye of a cat. Conventional nuclear detectors are installed in the nuclear core and are subject to extreme conditions. In the event of a disaster, such as that at Fukushima, the detector would be destroyed completely.
Beaumont and Joyce’s cat’s eye camera is a portable detector that weighs just 20 kilograms and can be activated well outside a nuclear reactor. It can be operated remotely and can generate images in near-real time. The camera consists of a detector plate situated behind a collimator (a type of filter) that has a slit shape hole, just like a cat’s eye during daytime. The hole limits the radiation that hits the detection plate.
Through its slit shape, the collimator can pinpoint exactly the source and the direction of the radiation and saves precious time to respond to emergencies. “If you use a traditional collimator, which is essentially just a pipe, then it can be swamped, it would be like looking at the sun,” said Joyce. “We can get an impression of where the optimum position on the other axis is, and then we are able to quickly move to that position,” added Beaumont.
The cat’s eye camera created by the researchers is an ideal instrument in monitoring and detecting the source and the level of neutrinos and gamma rays while a nuclear reactor operates, or in case of an accident. The device is described in the journal Nature Communications.
Anyone willing to pay can now access the Tesla FSD driver assistance beta
Elon Musk announced in a tweet that Tesla is opening up its so-called full self-driving (FSD) beta to anyone who has paid for it after gradually opening it up over the past few years. In North America, he added, “Tesla Full Self-Driving Beta is now available to anyone who requests it from the car screen, assuming you have purchased this option.”
With automated features like automated city steering, automatic parking, smart vehicle summoning, and traffic light/stop sign recognition, FSD builds on Tesla’s “Autopilot” driver-assist feature. The feature is a paid upgrade that costs $15,000 after a $3,000 price increase in September.

Congrats to Tesla Autopilot/AI team on achieving a major milestone!

Tesla initially stated that it would introduce fully autonomous driving features in 2018, but they didn’t actually do so until July 2021, to a select group of “careful and expert drivers.” The version 9.0 beta saw a wider release, but testers could only participate in an early access program. Tesla removed the requirements for at least 100 Autopilot miles and an 80 safety score on the most recent FSD release, so now anyone can get it.
However, Tesla is widely implementing FSD at a time when regulators are closely monitoring it. In a recent expansion of its investigation into a string of Tesla crashes involving first responders, the National Highway Traffic Safety Administration (NHTSA) is now looking at most models. It is also looking into more than 30 incidents involving Autopilot in a separate investigation.
Musk has long promised fully autonomous vehicles without a human driver. Most recently, he said he believed it might come this year, but in Tesla’s most recent earnings report, he backtracked on those statements. Following Elon Musk’s $44 billion acquisition of Twitter, the price of Tesla’s stock has been falling precipitously recently.
Importance of Physics in Different Fields
Physics is the foundation of other sciences, technology, and most engineering, which develops mathematical literacy. The most common complaint of a student usually sounds like this: “Why do I need to study this subject if I’m not going to do it after school” or “What are my benefits from studying this subject in the future”. This is due to the fact students face difficulties in physics studying during classrooms and in most cases, they require physics homework help online from real assignment experts.
Indeed, does a student need to cram formulas and deal with the laws of Newton and Faraday? Maybe, let’s do something interesting better? Surprisingly, even many adults do not understand why they taught physics at school and sincerely do not see the connection between this entertaining science and everyday life. Let’s find this connection.
So why do we need this science? Its task is to understand how certain phenomena occur, and why specific processes are formed. It also helps predict certain events. Have a look at the elevator, which quickly and easily takes you to the desired floor, different means of transport, computers, tablets, and phones – all of them won’t work without physics.
It is not just a school subject, it is something more. Many natural projects are performed with the assistance of physics, e.g. the simplest example of a physics process in life is the brewing of tea. This process is called diffusion. Weather is another great example: rainbow, shadow, refraction of light are all wonderful sciences. If physics did not exist in life, it is unlikely we would have such a convenient life now. This science is an irreplaceable thing in the life of every person.
Physics and Other Sciences
Physics is the basis for STEM subjects that are studied at a technical university. For example, electronics is a synthesis of several branches of physics: electromagnetism, solid-state and gases, etc. Even the queen of sciences – mathematics is a tool for physical research. Lasers are the physics of the stimulated emission of atoms and molecules. Holography is a technical use of the phenomenon of interference and diffraction of electromagnetic waves.
Chemistry is influenced by physics more than any other science. All chemical processes are the formation or destruction of bonds between valence electrons. In essence, theoretical chemistry is all physics.
Astronomy is older than physics, but it became a science when experts were able to explain why the planets and stars move exactly the way and not otherwise. The most startling discovery of astronomy was the fact that stars are made of the same atoms as Earth. This has been proven by spectroscopic physicists. Where do stars get their energy from? This became clear only by 1940, after the discovery of the fission reaction and thermonuclear fusion.
Furthermore, with the help of knowledge of physics and thanks to physical equipment helpers used in biology, the mechanism of all biological processes can be understood at the molecular and intracellular levels. DNA was discovered with the help of electron microscopes. What about the most complex processes of nervous activity? These are electromagnetic phenomena.
Clean air is required not only for a person but also for technological processes. Due to the presence of a large amount of dust, all equipment becomes unusable ahead of time. Escaping dust with gases is a very valuable process. This is since the purification of various industrial gases is extremely necessary today. Now, this problem is very easily solved by an electric field. How does it work?
Inside the metal pipe, there is a special wire that plays the role of the first electrode. The walls of the pipe provide the second electrode service. Due to the electric field, the gas in it begins to ionize. Negatively charged ions begin to attach to the particles of smoke, which comes along with the gas itself. Thus, they are being charged and begin to move to set on the pipe walls. After purification, the gas moves to the exit.
Thanks to physics, a huge contribution to the development of medicine has been made. The discovery of X-rays made it possible to identify various diseases of human internal organs and detect bone fractures. Specialists can measure blood pressure, use electric currents and magnetic fields for treatment, and other lasers and optical devices. Still, this is not a complete list of the greatest achievements and possibilities of physics in medicine.
Gravity, Momentum, and Other Availability
Physics discovers the principles of the law of gravitation. That is, we already know that if you throw an object, it will fall on the ground. What does it mean? The planet Earth pulls down us and all things. Moreover, it pulls down even such a heavy space object as the Moon. Also, any things that we throw on the floor, do not hang in the air because thrown objects are affected upon by acceleration created by gravitational and friction forces.
Therefore, knowing about these laws, you can understand what happens if you jump with a parachute. Is the area of the parachute related to the slowdown in the fall rate? Maybe you should ask for a larger parachute? How does the impulse work on your knees, and why can’t you land on straight legs?
How to choose alpine skiing? Are you a professional skater or an amateur? Think about friction, check these parameters for your new skis. If you are a beginner and have a lack of physics knowledge, then more likely you’ll probably make a mistake in ski selection.
Okay, you are not going to skydive, and you don’t want to know anything about alpine skiing. Let’s get back to everyday life. Here is a nut and a wrench in front of you. What part of the wrench should you grab to apply maximum force to the nut? Those who had physics assignments studied will take the wrench as far from the nut as possible. To open a heavy door, you need to press on it from the very edge, away from the hinges. Do we need to talk about the lever and the fulcrum that Galileo lacked so much? It is almost impossible to overestimate the importance of physics in all spheres of life. After all, it is everywhere: beginning from household and telephone to jetliners and space flights. It should be remembered that all the benefits of civilization became possible thanks to scientific discoveries.
Gotham: The Underrated Superhero Show
Superhero media is the hottest thing on the street right now. The Marvel Cinematic Universe is now over twenty movies in, with Avengers: Endgame being the second highest grossing film EVER, beat only by the 2009 film Avatar.
Super Hero TV shows are also incredibly popular, such as Marvels Jessica Jones, Daredevil, and Agents of Shield, but Marvel isn’t the only studio out there.
DC has produced some great films as well, most notably Wonder Woman, and has licensed out to CW several TV shows, including Arrow, Flash, and Super Woman, Legends of Tomorrow, and the upcoming Batwoman.
However, there is one Super Hero TV show that I feel deserves way more attention; the Fox Networks TV series, Gotham.
Gotham: Spoiler Free
Don’t worry, I won’t spoil anything in this paragraph. Gotham, in essence, is a five-season origin story for basically everyone in Gotham City. “But wait!” I hear you cry, “We’ve already had Batman’s origin way too many times. I’m sick of it.”
Yep, but I didn’t say Batman, did I? I said EVERYONE in Gotham city.
While the show opens with the iconic Batman origin, it’s done from the perspective of Jim Gordon, who’s just at the beginning of his career. You see, Gotham is more of an origin story for everyone other than Batman, and like a progressive jackpot, the more you’re in Gotham City the crazier you’re gonna get out of it.
What makes this show so good is that it presents all of the usual comic book absurdity while keeping everything grounded by presenting it all from the point of view of the do-it-by-the-books Jim Gordon.
If I’ve intrigued you, I highly recommend you stop right now and go watch Gotham, because I’m about to enter spoiler territory.
Gotham: Spoiler Zone
Still here? Good.
What sets Gotham apart from, say, the CW shows is that the Super Heroes and the good guys never get any powers. Not one. No super strength, speed, healing, or magical hacking powers. No Stark Tech, holograms, or alien alloys. You see, when the Flash can run so fast he can go backward in Time, it’s really hard to believe that he can ever be in any real danger.
In contrast, in Gotham, the heroes are always fighting the odds against these villains, and at the same time the villains are never so powerful they should be able to kill the heroes. That doesn’t mean the villains aren’t scary, though.
One of this show’s strongest points is its characterization. Everyone is incredibly well written, from the believable relationship of Alfred and Bruce to the stubborn Jim Gordon to the psychopathic Oswald Cobblepot.
Oh yes, the Penguin is here, and he is scary. He isn’t the fat fish mutant from the Tim Burton days. He is machiavellian and murderous, and although at the beginning we see him licking the boots of Gotham’s organized crime lords, I assure you it doesn’t stay that way.
Oh, and here’s a major spoiler warning. I really recommend watching the show before I gush about this part. There’s a love triangle.
With who, you may ask? Jim Gordon perhaps? Bruce? Harvey Bullock, perhaps? No, no, and no.
Gotham features a love triangle between Edward Nygma (the Riddler), the Penguin, and a woman named Isabella. Don’t worry, it’s better than that because the two men aren’t pining over the woman; Isabella and Penguin are both obsessed with the Riddler.
It’s as absurd as it sounds, and devolves into the chaotic jealous murder-fest that such an arrangement must inevitably fall into. It’s amazing.
Final Answer: Why should you watch Gotham?
So let me summarize why you should watch the underrated Gotham. It’s got great writing, amazing character arcs, unexpected plot developments, and a level of tension and stakes that other super hero shows are just… lacking.
By making Jim Gordon the focal point, the show presents a strong sense of morality and justice by making it really difficult to do the right thing in a corrupt and collapsing world, when half the time it’s easier to just keep you’re head down and look out for number one.
It’s easy to be a hero when you’re Super Woman, but it’s so much more meaningful when you’re not immune to bullets.
