![]() ![]() Other elements are not shiny, malleable, or ductile, and are poor conductors of heat and electricity. ![]() For example, many elements appear shiny, are malleable (able to be deformed without breaking) and ductile (can be drawn into wires), and conduct heat and electricity well. Many elements differ dramatically in their chemical and physical properties, but some elements are similar in their behaviors. Elements in the periodic table are organized according to their properties. For the table to fit on a single page, parts of two of the rows, a total of 14 columns, are usually written below the main body of the table.įigure 2. However, IUPAC recommends that the numbers 1 through 18 be used, and these labels are more common. In the United States, the labels traditionally were Roman numerals with capital letters. Groups are labeled at the top of each column. The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name. A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 2). The modern statement of this relationship, the periodic law, is as follows: the properties of the elements are periodic functions of their atomic numbers. You can view the transcript for “The Periodic Table: Crash Course Chemistry #4” here (opens in new window).īy the twentieth century, it became apparent that the periodic relationship involved atomic numbers rather than atomic masses. (credit a: modification of work by Serge Lachinov credit b: modification of work by “Den fjättrade ankan”/Wikimedia Commons) (a) Dimitri Mendeleev is widely credited with creating (b) the first periodic table of the elements. Although Mendeleev and Meyer had a long dispute over priority, Mendeleev’s contributions to the development of the periodic table are now more widely recognized (Figure 1).įigure 1. The discoveries of gallium (1875) and germanium (1886) provided great support for Mendeleev’s work. But Mendeleev went one step further than Meyer: He used his table to predict the existence of elements that would have the properties similar to aluminum and silicon, but were yet unknown. Both published tables with the elements arranged according to increasing atomic mass. Fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) also exhibit similar properties to each other, but these properties are drastically different from those of any of the elements above.ĭimitri Mendeleev in Russia (1869) and Lothar Meyer in Germany (1870) independently recognized that there was a periodic relationship among the properties of the elements known at that time. For example: Li, Na, and K are much more reactive than are Ca, Sr, and Ba Li, Na, and K form compounds with oxygen in a ratio of two of their atoms to one oxygen atom, whereas Ca, Sr, and Ba form compounds with one of their atoms to one oxygen atom. However, the specific properties of these two groupings are notably different from each other. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties.

![]() Apple has had eSIM in iPhones since 2018, so they’ve had some practice at this, but it was overall aggressively pleasant.Īdding my line even though I was “converting” from a physical SIM was painless. I added both to get the full dual-line experience and it went smoothly. This meant that when I booted up the devices for the first time I was presented with the option of activating that line or adding my own. This year, Apple shipped test iPhones to reviewers with a line of service attached. The winning colors that I saw in the hands-on area at the event last week were Purple, which brought back a shade close to the iPhone 12’s lavender and the (PRODUCT) RED, which is a really bold Pat McGrath-esque uber red that verges on magenta. The Blue in the iPhone 14 is fairly milquetoast in my opinion. Image Credits: Matthew Panzarino / TechCrunch If my initial impressions stand, I’ll likely just update this post. So this year I’m going to drop some initial impressions today based on testing some of the marquee new features and then I’m going to take a couple of weeks to layer on some experience-time with them. Typically I will try to fit in a solid experiential tour with the new devices because I prefer to have a real-world take on it by the time the public starts to get them.īut there is an enormous amount of time pressure there and I never feel like I’ve really lived in them long enough. I’d go so far as to say that Apple has pulled off a remarkable feat here in taking a reviled design concession - “the notch” - and turning it into a true tool that improves user experience.Īs a note, this year I decided to do something a bit different with my review of the iPhone. Through some lenses this actually makes them cheaper for much of the world - though the dollar’s relative strength has led to a higher cost in Europe and elsewhere.Įven the “ Dynamic Island” (a pill-shaped area that houses the iPhone’s front camera and other sensors) actually proves to be clever and useful. This year’s iPhones also defy inflation to offer better performance, better battery life and improved connectivity at the same price as last year. The cameras improve upon the already dominant iPhone 13 Pro’s arrays, especially in low light and telephoto performance. The always-on display does what competitors have done, but better and more logically. Apple is really leaning into its silicon lead to deliver big gains year over year in cameras, and it’s leaning on its design teams to give users new ways to interact with their very familiar devices. Apple’s iPhone 14 lineup delivers on a bunch of different vectors this year with very few peccadillos or complaints. ![]() ![]() When the men are captured by the Taliban, they spend more than 18 grueling months together in a prisoner of war camp. Buck Greene, was tasked with carrying out dangerous covert missions on behalf of the U.S. In the NBC reboot, Magnum was part of an elite fighting force made up of two Navy SEALS including himself and Sebastian Nuzo - who gets killed in the series premiere - and two Marines, Theodore “TC” Calvin and Orville “Rick” Wright. Why Magnum P.I.'s Signature Red Ferrari Is Still All the Rage In both the original and the reboot, Magnum is a former Navy SEAL and remains deeply entrenched in his military roots. Selleck and Universal Pictures donated the iconic ring to the museum after the original series wrapped up in 1988. “The Cross of Lorraine was a symbol used by the French resistance during World War II, and is featured in many film and television depictions of the French resistance including the 1942 film Casablanca.

The ring has a Cross of Lorraine inlaid into a black oval and is just another subtle nod to the original television series from the 1980s.

The price gouging is real because the 3400G is really the only option for gamers on a tight budget. The Ryzen 5 3400G should only cost $150, but you’ll find it selling closer to $290 these days. It’s less impressive at twice the price, though. It has been our go-to budget recommendation since it launched, and for good reason. ![]() It delivers 30 fps gameplay at 1080p for most AAA titles, and it’s a monster when it comes to esports or anything less demanding. As far as integrated graphics go, Vega 11 is the cream of the crop. It’s an APU that comes with four cores and eight threads, and importantly, Vega 11 graphics. The AMD Ryzen 5 3400G is a budget powerhouse. If you only have $500 to spend and don’t want to add a dedicated graphics card down the line, you should probably stick with a PS4 or Xbox One (or even a PS5 or Xbox Series console). It’s the best build under $500 you can get right now, but it’s still not ideal. This build is configured for upgrading down the line. For esports and indie titles, you can expect above 60 fps at 1080p with medium to high settings. That means a 30 frames-per-second target in most AAA games with low settings at 1080p. It’s a much better processor, though comes with much worse integrated graphics.įor performance, this machine should perform about as well as a base PS4 or Xbox One. The other option is to pick up something like the Intel Core i5-11600K. That said, it’s really the only in-stock option for gaming if you want to stay under $500. It’s overpriced, too, selling for twice its MSRP. Instead, we opted for a Ryzen CPU with integrated graphics. Our previous recommendation, the RX 570, usually sold for around $150. Unfortunately, the GPU market is in shambles at the moment, with even the most budget cards selling for well above what they’re worth. Our build doesn’t include a graphics card, which may be surprising for a “gaming” machine. Prices change, so make sure to check up on individual products before ordering the other components. We recommend you skip flashy features like RGB and opt for the core essentials that will improve your gaming.Altogether, this build comes out to $541 as of May 2021. Otherwise, choose budget-friendly peripherals with good gaming specs. ![]() If your current ones are good enough, use them. If you prefer immersive visuals, look for a monitor with excellent color accuracy. For competitive eSports, prioritize a high refresh rate. So, do your research and find the best monitor within your budget. Remember, you can upgrade components later, but changing monitors frequently is expensive. A good gaming monitor should be around 22 to 24 inches, but it depends on your preferences and space. If you already have one, great! But if you’re buying a new one, make sure it is 1080p in resolution with a refresh rate of at least 120Hz. When building a budget gaming PC, there are a few additional expenses to consider. $500 Gaming PC: Monitor, Peripherals, and Other Expenses Even so, our gaming PC managed to deliver decent performance on medium settings in those games.

Since the advent of the multi-tool market by Fein some years ago, no one else has come up with a true tool-free blade change system. Porter-Cable wins the innovation award for sure with their new PC250MTK Oscillating Multi-Tool. Given how many there are now, if you want your tool to stand out you need to be pretty innovative. Having spent time with nearly every oscillating multi-tool on the market has made it easy to spot when something is different. Porter-Cable PC250MTK 2.5A Oscillating Multi-Tool Kit Porter-Cable PC250MTK Multi-Tool Testing and Use High-Speed Steel Flexible Scraper Blade.4″ Half Round High-Speed Steel Flush Cut Blade.1-1/2″ by 1-5/8″ Bi-Metal Wood and Metal Plunge Cut Blade.1-1/2″ by 1-5/8″ High-Speed Steel Wood Plunge Cut blade.1-1/2″ by 1-5/8″ High-Speed Steel Precision Plunge Cut Blade.Here is a quick run-down of the accessories that come with the tool kit: The best thing with this tool-free system is that there are no removable parts, which is good for me because I tend to lose small things. The blades can be adjusted and locked into 30 degree increments depending on how they are inserted into the collet. ![]() The accessories each have nine holes that line up with the taped pins inside the collet. The pins in the collet are tapered so that, as both the tool and the accessories wear, they will always retain a tight fit and maximize the amount of torque the motor transfers to the blade. Simply give the spring-loaded metal arm on the bottom of the tool a squeeze and you can pull out the accessory from the collet. Now, where this oscillating tool is different than all the rest is the tool-free blade change system. The on/off switch is a sliding type that is located near the front top of the tool which puts it in easy reach for when you are holding the tool around the middle. The variable speed control allows for anywhere from 10,000 to 20,000 oscillations per minute (OPM) and provides 2.8 (total) degrees of oscillation. The PC250MTK comes with a 2.5 amp, high-torque, variable-speed motor that is controlled by a dial towards the back of the tool. The long cord means that you will probably be able to work on most things without having to use an extension cord. ![]() ![]() When we initially pulled out the tool we were shocked to find a 10 foot long cord tucked in the tool case. The overall body of the tool is made of gray glass filled nylon with about 75% of the outside covered with rubber overmold. The Porter-Cable PC250MTK Oscillating Multi-Tool Kit come all packaged up inside a sturdy black plastic tool case that has room to store the tool along with a decent collection of included accessories.

Mid-April is also the last average frost for our zone as of now, we could still get a heavy frost or even a freeze.For roses that were pruned hard in February, you may still have to cut out a few dead branches after the spring flush. Hydrangeas fall into this category as well it’s still too soon to know how hard they have been hit. Otherwise, you may be pruning out viable branches. ![]() Every day, damaged plants are showing new and unforeseen signs of life, even plants presumed long gone! Stay patient, and wait until mid April to prune out ‘dead’ branches, if at all possible. It’s still not time to aggressively prune.While each landscape is different, we have been seeing and hearing about signs of life. You aren’t alone sweet olive, loropetalums, lady banks rose, camellias, Indian hawthorn and even some needleleaf evergreens like Hinoke cypress and cryptomerias were hit hard.Here are some quick bullet points to keep in mind after this particular winter event: Below you will find all kinds of general information… but with the recent warm temperatures we have had in February and March, we have had tons of inquiries about just what can be done about plants that show severe signs of winter injury from our Christmas 2022 severe freeze. ![]() ![]() ![]() So what you might notice is that when I drew this, the horn came out straight. And let's just create a horn right in the middle of the forehead. Hit B to bring up our brushes, S for the brushes that start with S and let's get SnakeHook2. Let's go ahead and turn off symmetry mode. Now there's one other variant of the SnakeHook brush that I wanna show you. So just make sure that Sculptris Pro is turned on when using the SnakeHook brushes from now on. It doesn't quite know what to do with it. So if we turn this off and undo that, and then try to use it again, it's not really going to create much of an effect at all. Now this brush only works when Sculptris Pro mode is turned on. It doesn't peter out so you can create things that are as long as you want. So with Snake Sphere, the interesting thing you'll notice is that it maintains a diameter. So let's undo that and switch to a different brush. If you wanna create some really long tentacles or something, eventually it's gonna reach a point where it just kinda dies off. So one thing I've noticed with this is that you know, it's really great, it works nice but the effect kinda peters out towards the end. So let's just zoom out a little bit here and try something else. ![]() So let's undo that and just witness this as it happens. So you can see that it added little triangles all along to keep any one triangle from getting too stretched out. ![]() So let's turn on our wireframe with Shift + F and zoom in on that. And if we turn this on, it works great with SnakeHook because what it does is it automatically subdivides the model to maintain smoother topology. So there's a new feature in ZBrush 2018 called Sculptris Pro mode. So you can see what is doing is it's stretching out these polygons but at a certain point, it just becomes really, really difficult to maintain any sort of smooth topology with this. Now let's just use this to grab and pull on the model. And let's switch to the SnakeHook brush, B, S, and you can find it here, SnakeHook. Now with ZBrush 2018, there are some new varieties of the brush as well as a whole new feature that really allows SnakeHook to live up to its full potential. The problem up until now is that the affected head on objects is so extreme that it becomes unpractical quickly. The SnakeHook brush has been around for a long time and it does some interesting things. ![]() ![]() ![]() ![]() It can brew three cup sizes and has a 78-ounce water reservoir.
