When was the transistor invented4/2/2023 Marvin Kelley, who was then head of Bell Laboratories, had brought the trio together. In certain respects, a fourth person was responsible for the transistor being discovered at that time. Three persons, Walter Brattain, John Bardeen and William Shockley, shared the Nobel Prize in Physics for the breakthrough that they achieved on December 23, 1947. Yet the transistor is fundamental for all modern technology, including telecommunications, data communications, aviation and audio and video recording equipment. The inventors themselves believed that the transistor might be used in some special instruments and possible in military radio equipment. ![]() It was invented in 1947, and even several years later, it was considered by a scientific conference to be such an odd accomplishment that it was not included in the documentation. The transistor, however, is an invention that was conceived long before the time was right. This VOA Special English SCIENCE REPORT was written by Mario Ritter.Many inventions are conceived simultaneously by several different persons because the time is "right", meaning that a technical and scientific foundation exists and that there is demand and business potential for the invention. One scientist at Hewlett-Packard Laboratories worries that connecting so many molecule-sized devices together would prove to be almost impossible. Yet, the new extremely small transistors may be too small. They also say the chemical process for creating the transistors appears to work well. However, researchers at Bell Labs have already connected together several of the transistors into a circuit. The new transistor is still being developed. This simple ability to start and stop electrical current forms the language used by most computers. Releasing and stopping electrical current permits electronic processors to move and store information. The molecules also chemically form a molecule-sized device that controls electrical current. The process creates molecule-sized openings that carry electricity. ![]() The scientists used a chemical process to attach carbon-based molecules to gold. ![]() It is so small that it is put together chemically. Scientists Hendrik Schon, Zhenan Bao and Hong Meng created the new transistor. William Shockley, John Bardeen and Walter Brattain received the Nobel Prize for Physics in Nineteen-Fifty-Six for their discovery. In Nineteen-Forty-Seven, scientists at the same laboratory invented the first transistor. Lucent Technologies’ Bell Labs in Murray Hill, New Jersey, is developing the extremely small transistor. The area that carries electrical current in the new transistor is about the width of a single molecule. However, the new transistor may represent the smallest possible size for this kind of device. Scientists have developed smaller transistors year after year to produce more powerful integrated circuits. Powerful integrated circuits have large numbers of transistors. They form part of what is called an integrated circuit. They also have the ability to increase electrical current.Įxtremely small transistors are used in computers. True transistors can turn the flow of electricity on and off. Transistors are used in many electronic devices to control the flow of electrical current. It is about one-million times smaller than a grain of sand. Scientists report they have created the smallest device to carry electrical current ever made. ![]() This is the VOA Special English SCIENCE REPORT.

Animated gif in gimp 2.8.224/1/2023 Position where you would like the 2nd frame of the animation to be byĮither click and drag with the mouse, or click on the stack and use theĪRROW keys to move the stack one pixel in the arrow direction per press of theĪfter you have the stack positioned to where you would like the 2nd frame Next use the MOVE tool and move the LINKED layer stack to the Into position, while leaving the other layers in the stack LINKED so they In upwards order, set your mouse pointer on the bottom Since the GIF animation displays from the Bottom of the layer stack and Using the MOVE tool, move the entire layer stack to where you would like the first frame to display in the animation. Now that the layers in the stack are all LINKED, they will all move at the same time when using the MOVE tool (or the ROTATE tool, or will all be affected by several other transformation tools). In a GIF animation, the 1st layer to be displayed is the bottom layer in the GIMP layers stack, with the last to be displayed at the top of the stack. In GIMP, the top visible layer is the layer shown in front of the other visible layers on the screen. You should now see the link chains on all layers. (between the 'eye' and the small layer icon in the Layers window). The shortcut to do this is: hold the SHIFT key down, click on the LINK area to the left of any layers icon in the Layers box. Of the subject on the screen, as the duplicated layers have been stacked on top ofĮach other when they were created. Since the layers were all duplicates of the original, you should only see one copy Should are visible with the 'eye' showing next to them in the Layers tab window. With your resized canvas, check that all your layers The click the Resize button (shown in the image). Since you will be moving the subject layers to make the animation, there is no reason to click theĬenter option (but it doesn't matter if you do) and for the Layers option just use 'Resize layers: None' GIMP menu bar take Image > Canvas SizeĪnd set a new width and height (for this tutorial I have used 2000 x 20000) Now is a good time to resize (enlarge) your canvas so there will be room for the Now down at the bottom of the Layers box, find the Duplicate Layer button and click it as many times as When it is the active layer, the box around the layer's icon turns into a bold white square. Set your subject layer active by clicking on its icon in the Layers box. (you can add more during the process or remove the extras when your movement has been completed) When the layers have been placed to create the motion and everything is ready,Īfter the gif has been created, you can scale the image down to about 750 by 750 pixels to help keep the image file size low.Įstimate how many copies of the subject layer you might need. ![]() I will be using a subject layer size in pixels of 200 by 200 and a canvas size of 2000 width by 20000 height. To start, choose a subject and isolate it from it's background, or start with an image with a transparent layer and draw your subject. This simple tutorial does not use shadows or make adjustments for the laws of physics, it is just a 2D subject moving on the X (left and right) and Y (up and down) axis. Shows how duplicating your subject layer and using LINKS and the MOVE tool can make creating a Gif animation fast and fun.

Big weather umbrella4/1/2023 ![]() ![]() ![]() It can automatically open and close with the push of a button-like most automatics, you'll have to manually pull the runner down the steel shaft to completely collapse it. ★ Also great: The Balios Travel Umbrella ($24) is an equally excellent cheap umbrella that costs a little more than the Prostorm. This might not be an issue if your paws aren't as ginormous as mine (I'm 6'4"). My only gripe is the handle-the rubberized material feels nice (it comes with a strap!), but it's tiny in my large hands. It's double-vented with a 38-inch canopy that feels spacious for one person. It has a deeper dome than you'd expect for better protection, and the open/close mechanism works well, though you sometimes have to shake the umbrella to let it fully extend out. The fiberglass and steel frame feels slightly more robust, especially since it has nine ribs to support the canopy than the usual eight. The Prostorm Vented Travel Umbrella is pretty remarkable for the money-it's leagues better than the similarly priced models you'll find in corner stores on rainy days. It's more compact than The Stick, with a 40-inch canopy, but does the same great job of resisting such conditions. If you're in an area with high winds, consider The Collapsible Umbrella ($74). ★ Also great: I like Weatherman's The Stick Umbrella ($84), which is much bigger (44-inch canopy), only opens automatically, and has a vented canopy to allow strong gusts to flow through. It has one of the biggest arced domes to shield you from droplets too. It comes with a great strap, there's a lifetime warranty for any defects, and it has a little zipper pouch so you can store a Bluetooth tracker to help you track it down if you left it at a restaurant. That does mean the canopy is small-a smidge under 38 inches in diameter-making this a strictly one-person umbrella. It's one of the most compact umbrellas we've tested (save the Davek Mini below) and weighs less than a pound. I haven't noticed any issues with the open and close mechanism either. It's sturdy, thanks to its fiberglass ribs and shaft, and the Teflon fabric hasn't shown any signs of wear (it dries quickly!). ![]() The Travel Umbrella is my favorite-an umbrella that can automatically open and close is especially helpful as you enter a building while juggling groceries and a cup of coffee. Subscriptions help fund the work we do every day.Īfter testing a few Weatherman umbrellas for nearly two years, I think the brand offers the best quality for the money. com and our print magazine (if you'd like). Special offer for Gear readers: Get a 1-year subscription to WIRED for $5 ($25 off). Updated December 2022: We've added options from ShedRain. Now you just have to remember to bring it with you.īe sure to check our many other guides, including the Best Rain Jackets and our tips on how to re-waterproof your rain jacket. I've researched extensively and tested close to 40 umbrellas for nearly two years-these are our favorites at various price points. I also think it's worth spending a little more on a high-quality umbrella that will last a while. There are plenty of decent affordable umbrellas, you just need to know which brands to rely on. I've wasted a lot of cash on cheap umbrellas, and I'm here to warn you not to make the same mistake. A few months later, I'd bring out the same umbrella and it would already have small rips on the canopy or the stretchers would break and make a floppy mess in the wind. That's when I'd usually hit a corner store here in New York City to grab a cheap $20 umbrella. It always seems to rain when you least expect it.

Star wars episode 24/1/2023 ![]() ![]() "We knew going in that our cameras had a greater depth of field, 2 to 2 1/2 times greater than 35mm film," Meyers says. Hi-def videos extreme depth of field led the filmmakers to alter their blocking methods, as well as their approach to focusing on multiple actors in a shot. ![]() They didn't have to go by that proxy to do something as detailed as lighting or setting focus." They could actually see a scene and match the lighting on a new element with much more accuracy than watching through a videotap or on a telecine in editorial. What grew out of the technology were ideas for lining up new shots, and the ability to see on set exactly how a couple of elements might marry together. Meyers says Tattersall and his crew "started out doing things the way they knew how, but as they became more familiar with the digital cameras they gradually expanded from there. And later, there's no laborious film scanning required to get into editorial or the CG environment." "Also, you get immediate feedback on focus and exposure, so you can see exactly what you shot and know you've got it. "Even if you're aggressively shooting on hi-def, you're only reloading once a day, which ends up being a really big deal," Meyers notes. That way, it didn't look like a broadcast shoot."Īdvantages to shooting on HD included being able to review shots moments after they were captured, and the elimination of downtime for breaking out a new mag and reloading. Meyers key concern during production was to create an environment that wouldn't give Tattersall and his crew "culture shock." He offers, "I didn't want people walking onto the set and thinking, Whoa, this doesn't look like a normal shoot, so I hid all of the back end the recording, the camera control, the electronics off set. It was a great experience because I was able to work from the front of the project all the way through to the back." I worked through the entire pipeline, melding all of that into the workflow. You also need a person in the camera department to work with the camera operators, assistants and the director of photography, and then take it through editorial and visual effects to a digital intermediate and color timing. You need somebody to man the HD cameras and the support systems, including the digital recording and monitoring equipment on set. "It makes sense to have an engineer responsible for the digital cameras as part of the crew. "With all of the advantages and advances you get with digital, there's a lot more to attend to regarding all of the camera systems used in principal photography," he says. Meyers acknowledges that an all-digital shoot necessitated a significant level of technical support. That enabled some of the advantages of shooting digitally to percolate up as we went along." (For Tattersalls take on the production, see AC Sept. ![]() The interplay among the crew members just fell into place on the set. Because of that, we didn't stumble out of the gate everyone on the crew knew hed be doing what he knew how to do. We were fortunate to get camera accessories from Panavision that allowed the focus puller and camera assistants to work the way they normally would. "We wanted to put in a system that was going to run faster and more smoothly, so we set everything up exactly the same, only there were digital cameras and cabling. "Our strategy was, don't reinvent the process based on technology," Meyers says. Issues such as whether to employ members of a traditional film crew were settled quickly. In order to channel the crews creativity as effectively as possible, Lucas and Meyers agreed that it was best not to change a perfectly good system simply because the cameras were rolling tape instead of film. He was also the primary troubleshooter on the technical complexities presented by this new world. ∩9), Meyers was brought onto Episode II to ensure that film artists would make a fairly smooth transition to the digital realm. Expanding on his postproduction contributions to Star Wars-Episode I: The Phantom Menace (see AC Sept. Meyers' role on Episode II represents perhaps the first significant addition to the camera crew since the Technicolor color consultant. A key collaborator in both endeavors was Industrial Light & Magics HD engineer Fred Meyers. When George Lucas decided to shoot Star Wars-Episode II: Attack of the Clones with nascent digital technology, among the immediate concerns were how to configure the digital crew that would be headed by director of photography David Tattersall, BSC, and how to streamline a high-definition (HD) postproduction pipeline that would ultimately yield both digital and film versions of the show.

Premature birth: The babies born could be before 37 weeks and need close monitoring ( 6).Twin pregnancies can affect babies to an extent. How Can Twin Pregnancy Affect The Babies’ Health Here is the table indicating the required weight gain during pregnancy as per the BMI of the expecting mother ( 5). ![]() How much weight should you gain when you are pregnant with twins? But does that mean that you should gain more weight than in a normal pregnancy? You could also talk to the moms of twins and learn from their experiences.Ī bigger tummy is a prominent sign of twin pregnancy. Meditation and relaxation techniques along with the right diet can help you out of depression. Unlike in a regular pregnancy, the mothers in twin pregnancies get doubly exhausted, and have to feed more. Twin pregnancy is likely to increase the risk of postpartum depression as it takes the mother more time to adjust to the post-birth schedule ( 4).Wearing maternity bras can help reduce the pain. This is due to the hormonal changes, and by the sixth week, the aureoles and the nipples become darker and painfully sensitive. During the fourth and fifth week of twin pregnancy, you may have sore, tender, and painful breasts.The best way to sleep while pregnant with twins is on your sides with a pillow between your legs and under your tummy. Insomnia or lack of sleep is something that you may experience due to back pain, cramps, indigestion, nausea, and fatigue.Avoid spicy and oily foods, keep yourself hydrated, and take small but frequent meals to feel better. Digestion issues such as bloating, constipation, and heart burns are an early sign.Furthermore, a significant thrust by the baby in the uterus causes compression of pelvic parts leading to the enlargement of veins near the vagina. The increased blood flow puts pressure on the veins leading to varicose veins generally on the legs. Twin pregnancy requires more blood flow for healthy development of babies.You would be averse to the smell of food that can make you feel nauseated.Related: 4 Common Causes Of Food Aversions During Pregnancy
