![]() ![]() ![]() So according to the Royal Society of Chemistry, Mendeleev wrote the properties of each element on cards, and then he started ordering them by increasing atomic weight. But they weren't enough to usefully sort the 55 additional chemical elements known at the time. Gordin in his book "A Well-Ordered Thing: Dmitrii Mendeleev and the Shadow of the Periodic Table" (Princeton University Press, Revised Edition 2018). The first section of Mendeleev's book dealt with just eight of the known elements - carbon, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine and iodine - and those two strategies worked for those particular elements, according to Michael D. Just two strategies existed at the time to categorize these elements: separating them into metals and nonmetals or grouping them by an element's number of valence electrons (or those electrons in the outermost shell). At the time, there were 63 known chemical elements, each with an atomic weight calculated using Avogadro's hypothesis, which states that equal volumes of gases, when kept at the same temperature and pressure, hold the same number of molecules. Putting the elements in any kind of order would prove quite difficult. (Image credit: Oxford Science Archive/Print Collector/Getty Images) For instance, all the group 18 elements are inert gases, meaning they don't react with any other elements. Elements that occupy the same column on the periodic table (called a "group") have identical valence electron configurations and consequently behave in a similar fashion chemically. As an example, elements in Group 8A (or VIIIA) all have a full set of eight electrons in the highest-energy orbital, according to chemist William Reusch, on his webpage at Michigan State University. The columns, or groups, on the periodic table represent the atomic elements that have the same number of valence electrons, or those electrons in the outermost orbital shell. ![]() (Atoms have protons and neutrons in their nucleus, and surrounding that, they have their electrons arranged in orbitals, where an atomic orbital is a math term that describes the location of an electron as well as its wave-like behavior.)įor instance, period 1 includes elements that have one atomic orbital where electrons spin period 2 has two atomic orbitals, period 3 has three and so on up to period 7. The horizontal rows on the periodic table are called periods, where each period number indicates the number of orbitals for the elements in that row, according to Los Alamos National Laboratory. ![]()

While you may not be able to afford your own bat cave just yet, a smart lock is a strong starting point for your smart home security system. Smart home security systems are a great way to safeguard your home and ease the anxiety of unwanted visitors. And that is awesome. So let’s get started: You might have to make do with some commercial-grade or military-grade tech. Right now, there aren’t many iris-scanning solutions designed specifically for the home. Locking down your home with eyeball-imaging technology is a pretty innovative move on your part. The question then becomes, which iris scanner is right for you? Then you’ll have to wire those components for power and integrate them together.īut let’s say know a guy so you’ve got that covered. Typically, you’ll also need a securing mechanism, like an electromagnetic lock, and, for the more complex systems, possibly a server running access control software. You can’t just pop out the old deadbolt and insert your new scanner. If you’re still on board with locking down your pad like it’s Area 51, you’ve got some planning to do. The accuracy is comparable to an iris scan, but who has time for that kind of hassle? What you’ll need Getting that image means waiting for the pupil to dilate and then shining a beam of light through it to illuminate the back of the eye before taking the picture. Retina scanning is an older technology that uses an image of the nest of blood vessels at the rear of your eyeball. It’s worth mentioning that iris scanning is similar to retina scanning, but it’s not the same thing.

Like fingerprint matching, facial recognition software, and retinal scanning, iris scanning is a biometric technology that compares a person’s unique physical characteristics against a database to verify his or her identity. Most iris-scanning systems work by snapping a high-res photo of your eyes, isolating the iris portion of the image, then running that through a matching algorithm to see if you’re on the guest list. The iris, the ring of color around the pupil of each eye, is the most uniquely identifiable part of your body’s exterior (and much of its interior, for that matter). But if you want to take your home’s access control technology up a level (maybe five or six levels), then it’s time to start thinking about iris scanning. The Yale lock is a simple, effective mechanism that will likely still be around in another 150 years. That’s the year Linus Yale, Jr. patented the pin tumbler lock. If you’re like just about everybody, you lock your doors with a technology that’s gone essentially unchanged since 1861. ![]() ![]() ![]() At Riverview Gardens High School, she was a blond pompommer with a laugh that burst forth like a geyser, no stopping it.

Hupp, who’d held several jobs in the insurance industry, was the beneficiary of both her friend’s and mother’s policies. The only possible motive connecting all three cases was money. In the meantime, Hupp’s mother had died in a suspicious fall from a third-floor balcony. The friend’s husband was convicted and later acquitted. This was the same woman who’d testified three years earlier in a murder trial after her friend was stabbed 55 times.

![]() ![]() Not only in regards drastic reduction to the dreaded rubber-band effect and associated droning inherent with CVTs, but also in terms of returning a decent fuel economy figure, especially when compared to the outgoing six-speed automatics. In regards to how it actually works in the real world, reviews about this new transmission has been largely positive, with many saying that it is a marked improvement over many of the CVTs on the market today. Another benefit of this chain belt system is that it also has a longer lifespan and is maintenance free, which makes it more reliable. The first in the segment, it utilises the tension of the belt instead to adjust the pulley diameter, thus eliminating the instances of slippage and improving the efficiency in power delivery. So to address this issue, Hyundai has instead implemented a chain belt system in place of that metallic belt. A phenomenon that is especially common on small cars, where the pulleys apply pressure to the narrow area on the belt’s side to adjust the diameter. One drawback to this system though is that the pulleys and the belt often slip against each other, thus causing a reduction in transmission efficiency. It is then the contraction and expansion of said belt that alters the diameter of these pulleys, hence varying the gear ratio. One of which is connected to the engine output shaft, and the other is connected to the driveshaft. To those unfamiliar with the inner workings of a traditional CVT, an oversimplification of how this transmission works is that there is a metallic belt within the gearbox that links two pulleys together. Meanwhile on the responsiveness aspect, the new Shift Control Strategy featured with SmartStream IVT apparently reproduces the shifting pattern of a conventional automatic, which supposedly better reflecting the driver’s intent and driving conditions and therefore making it feel more responsive than the rubber-band effect normally associated with CVTs.Īll these bold claims from this Smartstream IVT, especially in terms of its efficiency, originates from one main innovation over traditional CVTs, and that would be the use of a chain belt instead of a metallic belt as the main power transfer mechanism within the gearbox. On the efficiency front, paired with a Smartstream G1.6 MPi four-cylinder in the new Elantra, an 8-speed variant of this novel transmission supposedly improves fuel economy by some 4.2%, and engine power loss by a margin of 5-8%. This is all because of Hyundai’s recent claims that its new SmartStream Intelligent Variable Transmission (IVT) is able to provide maximum efficiency, yet also be able to provide better responsiveness and smoothness compared to traditional CVTs on the market today. It is however the last one on the list that has been generating some considerable headlines as of late. The Korean automotive conglomerate is the only auto group in the world to currently have cars that feature all the four main gearbox types within its lineup: automatic, manual, dual-clutch and continuously variable transmissions (CVT). Here’s a surprising fact for the day, the Hyundai Motor Group is currently the only automaker in the world to comprehensively possess the technology for all transmission types. The clever new Smartstream Intelligent Variable Transmission (IVT) looks to be a giant leap forward over the conventional CVTs. ![]() ![]() The iPhone 13 has been released since our initial review, with revised camera dimensions meaning the latest 13 Pro and 13 Pro Max entries don't fit inside the Backbone One. ![]() The slim design means you can't connect the phone with most cases, even with the ultra-thin Apple MagSafe clear case, which adds barely 2mm of thickness. ![]() We first tested the Backbone One controller at launch with an iPhone 12 Pro Max and base iPhone 11.

The Backbone One supports any iPhone currently on the market, with its telescopic, spring-loaded design accommodating the full spectrum of Apple hardware from Pro Max to Mini. It's easy to get hooked on games, without thinking twice about controls, all tying back to the streamlined design.

It's incredibly comfortable for extended use, among the best solutions for ergonomics. The stick and button layout mirrors the Xbox controller, adopting the same ABXY configuration (a pain point when transitioning to Nintendo systems) with offset thumbsticks and commonplace inputs. It supports every modern iPhone with iOS 13 or later, hooking up over a direct Lightning connection, eliminating the added latency introduced by Bluetooth controllers. It's the closest alternative to a Nintendo Switch for mobile phones, emulating the split "Joy-Con" controls with an adjustable rail that scales the device's width for different screen sizes.
