Maya talks to people fighting insurmountable odds, including a woman forced to grapple with the news that she has a 50-50 chance of carrying a deadly genetic mutation. “I was forced to try and figure out who I was, and who I could be, without the violin." Maya soon discovered a new path in the field of cognitive science, where she earned her PhD as a Rhodes Scholar studying how and why we change. And, as always, you’ll hear stories about navigating the uncertainty that comes along with change. “My whole childhood revolved around the violin, but that changed in a moment when I injured my hand playing a single note,” says Shankar, who was studying under Itzhak Perlman at the Juilliard School at the time.

Roberts High School who has a true passion for the weather. This one-two punch will be remembered in local and national history books, but it seems that it was a crazy day suitable for 2020. Obviously, having two separate and severe storms on the same day is an unusual occurrence especially for this part of the country and especially when the storms are presented in two completely different ways. It was a little surprising that we could have two separate rounds, each with such severity.”īased on O’Brien’s impression, it is evident that this was a notable day in the careers of many local meteorologists. ![]() “Normally, once you get one round of severe storms, especially as severe as the derecho, it stabilizes the atmosphere which holds off storms until at least the next day. He said the storms were forecasted well, even the possibility of two distinct rounds. ![]() O’Brien was the one who issued many of the warnings on that busy day. I cannot think of any other examples like it,” said Jonathon O’Brien, a meteorologist at the nearest National Weather Service station in Mount Holly, N.J., while referencing the sequence of events. “This was pretty rare, especially for this part of the country. Luckily, no deaths resulted from this punch, but the damage was still prominent and lasting. Many were still operating generators from the morning storm as the second storm hit. While a tornado never touched down, damaging winds and hail were seen once again across the area, bringing power outages to a total of 850,000-plus for the day. These are the storms that are most likely to produce tornadoes and, in fact, this fear almost came to fruition as Philadelphia was placed under a Tornado Warning as the storm approached later in the evening. However, that does not limit their power. These storms are different from derechos because they exist as a single cell, meaning they are much more localized. ![]() It also dropped heavy downpours accompanied by small hail in some regions.įlooding, flying debris, phone lines and trees ripped from the ground, and property damage were some of the many effects felt region-wide. Soon after, residents felt the wrath of the storm through extreme wind gusts – some examples include 83 mph in Reading, 76 mph in Pottstown, and even 93 mph at the Jersey Shore. First, an ominous shelf cloud resembling a multi-layered cake led the storm by only a few minutes. Unfortunately, such standards were achieved last year across the region. On June 3, 2020, around midday, a derecho thunderstorm roared across Eastern Pennsylvania, New Jersey and New York, and, as many may remember, brought with it lasting effects.ĭerechos are bowing lines of thunderstorms that produce at least 240 miles of wind damage and have continuous winds of at least 58 mph, bringing a severe risk to life and property.

That’s not surprising, as it’s a day that made weather history. ![]() ![]() Even if you don't have a MacBook Pro with Touch Bar, you can take advantage of BetterTouchTool's other customizations for the Magic Mouse and Magic Trackpad. It won't brick your Mac, and quite frankly, it's such a good customizable tool that it should be on everyone's Mac. Though you can't download BetterTouchTool from the Mac App Store - it's the kind of app that requires far too much system hook-in to be properly sandboxed under Apple's rules - it's still a solid app from a respected developer. Better Touch Tool isn't in the Mac App Store - but you should still own it I suggest browsing around the predefined actions to see everything you can do. You'll have to allow it to control your computer through your Security & Privacy's Accessibility. If you're interested, download BetterTouchTool and then move the download into your Applications folder to get started. One Touch Bar action I created for Slack - thanks to a little help from Alex W - included a shortcut that let me switch between chat rooms with just a tap. Pros: Adds sorely missed functionality to trackpad / magic mouseīoth straight forward, but also with advanced tweaks and settings availableĬons: Possibly buggy? (I installed version 0.Open a specific app you've built Touch Bar actions for, however, and the bar will shift to displaying those buttons instead. I have only installed it this week, and so far no issues with bugs. I don't know if you have used Win 7 at all, but to my mind one of the best features is the 'windows snapping' to resize windows (if not - it means by dragging a program window to various places it changes size: to the top of the screen and it maximizes, plus to each edge for half screen left/right).Īnother missing feature, one of the best features of an iphone / ipod touch / android phone, is 'pinch to zoom': by moving two fingers closer together / further apart changes the size of text etc on a web page etc. Very good tool for adding a couple of missing features to touchpad/magic mouse, for example: It also does not help that the app lacks instructions, and there isn't that much information about the app available. However, understanding how each function works may be challenging for inexperienced users. It is also lightweight and does not require too much maintenance. The app functions well and gives users control of their device's gestures. ![]() Overall, BetterTouchTool is a must-try if you wish to improve your Mac computer's organization. It is also low maintenance and does not need constant updates. However, you will be happy to know that the app comes in a lightweight package and works fast. If that's the case, restarting the app from the menu bar should do the trick. Additionally, the shortcuts you set up occasionally stop working. Users should also note that some modifications require system preferences changes. And although the overall interface is good, it can be a little confusing. Additionally, the features are a little difficult to interpret outside the main menus. ![]() Users will also notice the lack of instructions, which is a pity since understanding all its functions is not that simple. However, after initial startup, it will attempt to access all of the computers on the test network. Not for the inexperiencedĪvailable as freeware, BetterTouchTool is easy to download and install. It also comes with a screenshot tool allowing you to adjust images on the fly. This tool also comes with an integrated clipboard manager to copy multiple items at once. Moreover, you can specify which app the shortcuts will apply to and which will be disabled. You can also dream up unusual key sequences, movement gestures, and even drawings to replace default options. Even better, it also comes with a BTT remote, offering a way to receive remote input through a free Apple device app.īetterTouchTool also allows users to create any shortcut by recording newly expanded shortcuts for any device. Moreover, it also accepts input from paired Siri Remote, MIDI triggers, and key sequences. The app centers around input methods, assigning trigger sets to common items, such as a trackpad, Magic Mouse, or regular mouse, keyboard, and Touch Bar. One of the things you will appreciate about the app is the range of input devices it lets you control. As mentioned, this tool allows users to customize and configure their trackpad gestures completely. Among the growing list of utility apps is BetterTouchTool. Luckily, there are a chock-full of great Mac apps that can elevate your daily computing life. Some find it not particularly flexible, while others think it lacks essential features. For average Mac users, the trackpads default functioning is sometimes frustrating. ![]() Each brick has a number in it that indicates how many times it needs to be hit before it's destroyed. They will bounce and ricochet off the sides of the level and the bricks themselves until they return to the bottom of the screen. You start off with a set number of balls that will fire all at once in a line. The goal of each level is to clear out all the bricks on the screen in as few moves as possible.Įach level will load an arrangement of bricks that descend after every one of your shots. On the game screen, click and hold the circle at the bottom and drag it around to choose your trajectory then let go to launch the balls.

How to Playīricks Breaker Deluxe is a 2D breakout-style game that can be played using only the mouse. This is a chance to prove that you can break things efficiently. Things like achievements and currency for power-ups are commonplace nowadays and can be very helpful in making you more effective at breaking things. Not just with all the neon lighting but a lot of the mechanics and gameplay elements that we've come to expect in modern gaming. This game is quite clear that it's inspired by the classic title but wants to add more flair to it. Once again, we must look back to Atari and remember the popular Breakout game that has been remade, revived, and recreated in numerous ways. Launch everything you have across the sign to break everything and hold onto whatever you can so that you can keep on breaking bricks. If there aren't things glowing then you've stumbled into the wrong place. You're going to a neon rave sign to play a game with glowing balls, glowing blocks, glowing numbers, and glowing diamonds. This is because "break" is right there in the title so you know what to expect. The game is suited for players who like games inspired by Breakout.Sometimes you just want to break things and that's why video games are such a great outlet for that, especially with a title like Bricks Breaker Deluxe.The more hits it takes to remove a brick, the higher its point value is.For instance, an orange block will be worth 2,000 points.If a brick started out as a different color, the points you’ll receive when you it are much higher.You receive 1,000 points for every red brick you break.Large paddle: Temporarily lengthens your paddle.Small ball: Shrinks your ball temporarily.Extra balls: Get two more balls bouncing around.You can receive the following power ups:.The bricks you break will drop power up cubes.Lose all your lives and it’s game over.Each time you fail to catch the ball, you lose a life.Keep playing until you run out of lives.After you clear one set of bricks, a new one loads.Move the paddle to catch the ball and keep it in play. ![]() Hit green bricks to turn them into yellow bricks.Hit yellow bricks to turn them into orange bricks.Hit orange bricks to turn them into red bricks.Red bricks are destroyed immediately with one hit.Depending on their color, the bricks will either change color or disappear.You cannot move the paddle when you are about to launch the ball.Use the arrow keys to change the direction of the ball on launch.Launch the ball onto the bricks on the top of the screen.Controls and indicators (bottom center, top-down).Although this game might load on touchscreen devices, its controls were optimized for desktops with keyboards.After a game over, press the F5 key to restart the game.Press the left and right arrows to move the paddle.Press the space bar to launch the ball.Your high score appears on the bottom center of the welcome screen.Your web browser automatically saves your high score.On the welcome screen, press the enter key to start.Catch the ball with the paddle to keep it in play.

Depending on the range of shear rates available in Viscosity Measurement different parts of the curve will be accessed for different liquids. The absolute position of this curve on the viscosity and shear rate axes depends on the particular non-Newtonian liquid being investigated, as does the slope of the power-law region, as well as the possible upturn at high shear rate. At low enough shear rates, the viscosity is constant, thereafter decreasing through what is called the power-law region, to eventually flatten out a higher shear rates, often to become constant again, but sometimes rising. The (almost) universal behavior of all such liquids is shown in Figure 2. The most important variation of viscosity for non-Newtonian liquids is with shear rate. Its dependence is such that at the normal pressures found in heat and mass transfer operations, it can usually be neglected. The viscosity of liquids almost always increases with pressure, with water being the sole exception. Around room temperature, the viscosity of water decreases by 3% per degree Celcius oils by about 5%, and bitumen by 15% or more. The temperature dependence of the viscosity of Newtonian liquids is such that the viscosity decreases with temperature, and in general, the higher the viscosity, the greater the rate of decrease with temperature. (Prior to the introduction of the SI system, the cgs unit relevant to low viscosity liquids was the centipoise, which is identical to the mPas.) A form of viscosity often referred to is the kinematic viscosity, ν m 2s −1 which is the quantity we have defined above divided by the density of the fluid, ρ, i.e., ν = η/η. The units of shear stress are Pascals (Pa), shear rate reciprocal seconds (s −1), and so the unit of viscosity is the Pascal-seconds (Pas or Pa.s), with mPas being the more usual unit used for low viscosity fluids. The ratio of these two quantities is the viscosity hence η = σ/ The shear rate (sometimes called the strain rate or velocity gradient), which is the proper measure of the rate of deformation in the fluid undergoing shear flow. In shear flow-where we imagine the flow as hypothetical layers of fluid flowing over each other-we define the relevant parameters as (see Figure 1) σ the shear stress (force per unit area) at the boundary of the fluid to produce the flow, and Quantitatively, viscosity is defined as the stress in a particular ideal flow-field divided by the rate of deformation of the flow. ![]() Viscosity can depend on the type of flow (shear and/or extensional), its duration and rate, as well as the prevailing temperature and pressure. Viscosity is that property of a fluid which is the measure of its resistance to flow (i.e. |
