![]() "Our larger (UCS series) sets often require an internal frame constructed with mostly LEGO Technic elements to make them stable and sturdy enough. Seeing Crosshair’s new set of armor for the first time made me very excited to watch the new Bad Batch series! I can’t wait to see how and why he gets it."ĭesigner Hans Burkhard Schlömer on making a kid-friendly play set for Star Wars fans 9 and up. We wanted to make sure to capture all of these fun features in the minifigures, and we created a few new elements to help with that as well. Also, despite the fact that they are clones, they each have unique facial features whether that be scars, face paint, goggles, tattoos, and even cybernetic implants. "Each member of the Bad Batch has a distinct personality and a unique set of armor. Senior Graphic Designer Madison O'Neil on creating those amazing new minifigures - including a revealing look at Crosshair. is excited to exclusively debut the new Star Wars: The Bad Batch Attack Shuttle from the LEGO Group, including insights from the team that helped create it. (Hint: One of these clones is looking a little different than his brothers.) Star Wars: The Bad Batch has arrived on Disney+, and today the LEGO Group has revealed a new buildable playset inspired by the unique squad's ship. The set includes six minifigures - Hunter, Tech, Wrecker, Echo, Crosshair, and a Gonk droid - and at least one spoiler from the super-sized premiere. ![]() Beyta, First Officer Hawkins, Chopper and a decidedly not green-headed Jacen Syndulla.Hunter, Tech, Wrecker, Echo, and Crosshair hit the bricks after Order 66. ![]() Regardless, you can get your hands on your own LEGO set on September 1, 2023, along with “Ahsoka Tano’s T-6 Jedi Shuttle”-with minifigures Ahsoka, Sabine Wren, Huyang and the Inquisitor Marrok-and a brand-new “Ghost & Phantom II” build, including minifigures Hera Syndulla, Lt. The question is: Will this new canon E-Wing go the way of the ship of Legends? Or, seeing as the starfighter doesn’t appear in the Resistance fleet, does it meet with some unfortunate end? Is it phased out, or commandeered? Will it continue to be the New Republic’s first bit of starfighter glory, or another testament to the government’s inevitable failure? The E-Wing itself is an example of Ahsoka’s own words: “There’s always a bit of truth in legends.” Animated LEGO to plastic LEGO to actual ship. In a way, the jump from The Freemaker Adventures to Ahsoka by way of a new LEGO set makes sense. In both cases, the E-Wing was more of a collector’s piece than a formidable starfighter. So, where has it shown up? It’s first canon appearance was in Charles Soul’s comic Poe Dameron 23 its first non-canon appearance was in an episode of LEGO Star Wars: The Freemaker Adventures entitled “The Embersteel Blade.” That episode committed the E-Wing’s developer, FreiTek Inc., to canon-from a certain point of view. The Resistance in the sequel trilogy continues to rely on the X-Wing, and we’ve seen no hint of the E-Wing in other live-action Star Wars projects. We’ve already seen Palpatine resurrected in current Star Wars canon-and we’ve also already seen the E-Wing, though barely. Its versatility, speed and shields saw the E-Wing gain in popularity, and it continued to play a role in galactic combat throughout the Second Galactic Civil War. Nonetheless, the E-Wing was used by the New Republic in response to Grand Admiral Thrawn’s attempt to rebuild the Empire, and later to combat the resurrected Emperor Palpatine. Unfortunately, it wasn’t as reliable, and pilots continued to resort to the older, more trustworthy starfighter. Introduced in Tom Veitch’s 1992 comic Dark Empire 3: The Battle for Calamari and developed by FreiTek Inc., the hope was that the new E-Wing would replace the legendary X-Wing. In Legends, the E-Wing was the first starfighter commissioned under the New Republic. ![]() I went down the rabbit hole on the E-Wing so you don’t have to. The wings don’t open into that classic X-formation but curve downward-like an X-Wing if you tore off one of the S-foils and hopelessly bent the other.īut that all makes sense. It’s got the feel of a New Republic X-Wing: blue lines over a metallic-white body. Take a look at that New Republic E-Wing escort starfighter. The set in question: “New Republic E-Wing vs. But a day when the build in question is a ship I’ve only ever seen mentioned deep within the archive of books now considered Star Wars Legends?

This is a great chance for all junior UX designers out there to work with a team of designers alongside a skillful mentor, to add a brand-new case study to their portfolio. I've been asking around about the challenge, the workshops, and the mentorship they offer during the challenge for the past couple of months (because I wanted my money well-spent), and all the people that I asked were completely satisfied. That's why I wanted to get my hands on as many team projects as possible before the end of summer and I registered for the IterateUX design challenge. It's unbelievable how much you learn while working with other designers, and how much your portfolio case studies stand out among all the boot camp projects. "Building products with a team of designers" ![]() I wish I knew sooner that the fastest way of growing as a junior UX designer is this: Before you know it, you might accidentally discover something that is a perfect fit - and that is worth it. Explore what other roles are in your company. We should look much broader. Design isn’t a single role, it’s a wide spectrum of roles. However, over time we can improve the shape of our cognitive functions depending on our experiences.Īs Bas writes, the tests are not reliable enough and personalities are just a small part of who we are. Keep in mind that each person has many cognitive functions, one of them is primary and the three others supplement our primary function. Instead, it can be a helpful tool for designers to find out where they would love to move next, or what directions they would like to explore. Don’t see it as a framework for design managers to figure out where an employee would fit best. ![]() Tasks and responsibilities might vary significantly between teams - even within the same organization, so consider carefully how to apply the role to your context, but a general visualization seems to be quite accurate.Īlso, I’m always skeptical about personality tests and mapping specific types of people against tasks, strengths and weaknesses. Personally, I’d love to emphasize that roles might mean very different things in different companies. ✅ Effective conflict managers, UX researchers, interaction designers. ✅ They can build relationships like no one else can. ✅ FEELERS want to understand their own emotions and those of others. ![]() ✅ Great data analysts, service designers and fit design system roles. ✅ They can manage complexity like no one else can. ✅ THINKERS use an analytical approach to make decisions. ✅ They make for great product designers and UX designers. ✅ They see opportunities and connections no one else sees. ✅ INTUITIVE people imagine the future and focus on big-picture ideas. ✅ They make for great team leads and product managers. ✅ They see details and patterns that no one else sees. ✅ SENSING people prefer to use their senses over imagination. ✅ Each person combines many cognitive functions. ✅ There are 4 cognitive functions: Sensing, Intuition, Thinking, Feeling. ✅ Bigger organization → more specialized roles. ✅ But usually will have a strong focus in a few. ✅ You might operate in many segments at times. □ It’s impossible for a single person to cover all design needs.

Ford incorporated the higher drivetrain tunnel that was required in a lower car into a center console dividing both front and rear seats which featured ashtrays, switches, and minor controls. The 1958 Thunderbird was only 52.5 inches tall, nearly 9 inches shorter than an average American sedan the Thunderbird had only 5.8 inches of ground clearance. The intent was to allow the maximum interior space in a relatively small exterior package. The four-seat Thunderbird was designed with unibody construction, eschewing a separate chassis shared with the all-new Lincoln built at the all new factory in Wixom, Michigan. However, the losing proposal, styled by Elwood Engel, would gain its own place in Ford Motor Company history: after minor revisions, it would become the 1961 Lincoln Continental. The design was one of two proposals, styled primarily by Joe Oros, who later worked on the 1964 Ford Mustang. The design was driven entirely by the styling department and approved before the engineering was considered. The new Thunderbird had a distinct new styling theme. ![]() Mercury also saw the introduction of a flagship hardtop coupe with a similar approach to luxury called the Mercury Turnpike Cruiser with a longer wheelbase and two inches more for width dimensions, then updated to the 1958 Mercury Park Lane. The listed retail price was US$3,408 for the base price ($35,509 in 2022 dollars ). As a response, Ford executives decided to add a rear seat to the Thunderbird. The Studebaker Speedster and the Chrysler 300C shared many appearances with the Thunderbird, while offering a rear seat. Market research suggested sales of the Thunderbird were limited by its two-seat configuration, making it unsuitable for families. ![]() Īlong with the 1958 Lincolns, the 1958 Thunderbird was the first Ford Motor Company vehicle designed with unibody construction.Īlthough the 1955-1957 Ford Thunderbird had proved successful (in comparison to the Chevrolet Corvette), Ford executives-particularly Robert McNamara-still felt its overall sales volume had room to improve. Sales totalled 198,191 over three model years, approximately four times that of the earlier two seat model. In response to Ford-conducted surveys two major changes were made to attract potential buyers: two rear seats were added and the level of luxury and features of a full-sized car were incorporated into a mid-size platform.Īs a result, sales soared and the new model dramatically expanded the personal luxury car market, winning the Motor Trend Car of the Year in 1958. The second generation Ford Thunderbird (also called Square Bird ) was produced by Ford for the 1958 to 1960 model years as a successor to the popular 1955–1957 two-seater. ![]() If ((scaleOutput.indexOf(".") = 8) || (scaleOutput.indexOf('. ![]() The SCI is more widely used than the SPI, and can communicate over longer distances.

Use the term font when you a referring to one particular alphabet of size and style of a typeface.Typography says a lot about your online brand. To summarise, use the term typeface for identification purposes and when you are discussing look or style. However, I think it’s always nice to preserve a little bit of history, so when you can try and use the terms correctly. Especially when using and selecting fonts within software. Well, you’re not going to be outcast from the typographic community if you happen to use the terms incorrectly. Does it Really Matter if a Say Typeface or Font? I guess maybe this is to do with being able to select both the typeface and font style from the same menu? Maybe I’m clutching at straws here!Īs you can see, things aren’t so black and white when trying to determine whether to refer to typeface or font within a software program. Why have Adobe decided to use the term font family and not typeface? So you may refer to a typeface as having a large family if it contains lots of different styles. For example, Helvetica Regular, Helvetica Italic, Helvetica Bold, Helvetica Condensed etc. The same can be seen within the New Paragraph Style box with InDesign.Ī font family refers to all the different styles within a single typeface. One thing to take note of is the terminology used on the tool tip when hovering over the font (or is that typeface?) name in Illustrator. This makes sense as you are always only selecting a single alphabet of one size and style at any given time. Referring to any of the Adobe applications such as InDesign, Photoshop or Illustrator the terminology used is font. When using software things can get a little more confusing… “You need to change the font to bold so it stands out more” So How Does This Apply When Using Software? “You need to make the font larger as I cannot read it” “Change the font to Garamond, 14pt, italic” Therefore, a font is one alphabet of a particular size and style of a Typeface. ![]() Each one of these draws (type cases) contains a single font. For example, one draw (type case) of would contain Helvetica 12pt regular and another may contain Helvetica 12pt Bold. It has a special organizational system and houses both the upper and lower cases of one size and style of a typeface. The type case is a single draw within the type cabinet. “Erik Spiekermann is one of my favourite typeface designers”. “Times New Roman is a serif typeface and was designed for the British newspaper The Times” “ITC Officina Sans is one of my favourite typefaces” When speaking, you might use the term typeface like this: Typefaces may be called after their designer such as Baskerville or Garamond a country such as Egyptian or just a name like Myriad. ![]() Therefore, a typeface refers to the design or look of alphabet and is used for identification purposes. For example, a type cabinet for Helvetica would contain multiple alphabets of metal characters of varying sizes and weights with each stored in their own draw (type case). Obviously, there needed to be some sort of organizational system which would enable the typesetter to find the required characters, so the type cabinets contained a number of compartmentalized draws called type cases.Įach type cabinet would house a single typeface. The Type CabinetĪs you could imagine, there were thousands of these metal characters and they were stored in large wooden cabinets. It is where these metal characters were stored that hold the answer to the typeface vs font debate. ![]() Yes, page layout was a very time consuming process in those days! Back in the day, type was set manually by placing re-usable metal characters into a chase (which is basically a frame), ink was applied to the letters and then this was pressed onto paper to produce the finished printed piece. A Trip Back in TimeĪs with most typography terminology it originates from the pre-digital world of analogue typesetting. Then I’ll explain how these terms are used in todays context and how they are used in popular software programs like the Adobe Creative Suite. ![]() To gain an understanding of where these two terms originated from a quick history lesson is in order (but don’t worry I’ll make it interesting). So, what is a font? And what is the difference between font and typeface? Typeface vs Fontīut the great thing is with a little knowledge you’ll be soon using both terms like a pro.

Baratza stripped the Encore of complex and advanced features to make it easy to use and make it efficient in grinding. It is an exceptional grinder at this price point. The Baratza Encore retails at below $150. ![]() With a grind range of between 250 to 1200 microns, you will hit the sweet spot with ease. The coarse ground may not be as consistent as the espresso ground, but consistency doesn’t matter much when making cold brews. The grounds can be fine enough for espresso, but I recommend you use a pressurized portafilter to get impressive results. This Baratza grinder excels in grinding consistency, ensuring that your coffee is smooth. This burr grinder is very popular for manual brewing methods such as French Press or Chemix. You can produce superfine grinds to very coarse grinds, depending on the kind of coffee you need to brew. Rotate the hopper as you check the marked settings at its base. With 40 grind coarseness settings, you can customize the ground based on the brewing method you need to use. Overall, you can expect this Baratza burr grinder to serve you for a long time. It has a plastic case that is thick and sturdy to enhance its durability. Further, the collection bin holds 5 oz, which is standard for coffee grinders. Its 8 oz hopper offers enough capacity to grind enough coffee for you. The gears inside the unit feature 15 percent thermoplastic glass that ensures they operate quietly, are shock-resistant, and they last long. This burr grinder has a powerful high torque dc motor which is a nice option considering the price. Unless you prepare 10 or more brews at a time, the grinder stays cool. However, the unit doesn’t often overheat. Its high torque gearbox features a thermal overload protection that cuts off power if the motor overheats. Grinding cool beans retains their flavors. This is not the fastest in the industry, but it ensures that heat doesn’t build up and the beans remain cool. The steel burrs in the Baratza Encore are 40mm thick and in a conical shape. This is more flexible than other coffee grinders in its price range offer. ![]() With 40 coarseness settings, you can adjust grind size to fine coffee for espresso or coarse one for French Press. At the base of the bean hopper, there are calibration system options to show the level of adjustment. With this Baratza grinder, you have 40 coarseness settings. This increases or reduces the gap between the burrs and consequently the size of the grind. To adjust the grind size, you need to rotate the bean hopper right or left. After grinding, the grounds fall onto the plastic collection bin in the hopper below. These burrs have sharp edges and grooves that make them effective at grinding the beans. The burrs have a heavy stainless steel build. It sports a transparent bean hopper that funnels the coffee beans to the conical burrs. Its profile is similar to that of many powered coffee grinders. Its extra weight and strong plastic construction make it durable. It is a compact grinder, but it is heavier than it looks. The Encore stands at 13.3 inches tall and is 5.5 inches wide with a depth of 6.3 inches. You do not need to be an experienced brewer to adjust the grind settings on this burr grinder and it’s considered to be an entry level grinder. Rotate the hopper until it gets to the grind setting of your desire. You only need to turn it on by pressing the on/off button on its side and adjusting the grind setting. The Encore is an automatic grinder, and this makes it easy to use. Most importantly it produces consistent grinds.īelow are the ratings of this coffee grinder. Once again the powerful high torque dc motor is a great feature in this burr grinder with up to 550 rpm burr rotation. It is easy to use for beginners and even when your brewing skills improve, you may never need an upgrade. ![]() There is a pulse button on the grinder that allows you to grind coffee on demand. Slow speed reduces heat noise, by cooling the beans, the grinder ensures that the oil in the beans remains intact and the coffee doesn’t have a bitter flavor. This is not common for coffee grinders in its price range. Inside the grinder has a powerful high torque dc motor that ensures the beans remain cool during long grinding times. The Baratza works great for the following brewing methods: With a grind range between 250 to 1200 microns, the grinder allows you more than one brewing method. It grinds uniformly, allowing you to create the perfect cup of coffee. ![]() This makes it easy for you to produce the perfect grind. Baratza Encore is a beginner grinder and an entry level grinder with 40 grinder settings options. ![]() Building nuclear reactors requires a high level of technology, and only the countries that have signed the Nuclear Non-Proliferation Treaty can get the uranium or plutonium that is required. The first nuclear power plant designed to provide energy to a community was established in Obninsk, Russia, in 1954. The Experimental Breeder Reactor began powering itself in 1951. The first nuclear reactor to produce electricity was located near Arco, Idaho. Nuclear Energy and People Nuclear energy produces electricity that can be used to power homes, schools, businesses, and hospitals. This reduces the amount of mining, extracting, and processing that needs to be done. Complex processes allow some uranium and plutonium to be re-enriched or recycled. A typical nuclear reactor uses about 200 tons of uranium every year. The treaty promotes the peaceful use of nuclear fuel, as well as limiting the spread of nuclear weapons. Because nuclear fuel can be used to create nuclear weapons as well as nuclear reactors, only nations that are part of the Nuclear Non-Proliferation Treaty (NPT) are allowed to import uranium or plutonium, another nuclear fuel. It must also be processed before it can be used. Once uranium is mined, it must be extracted from other minerals. gets uranium from Australia, Canada, Kazakhstan, Russia, and Uzbekistan. U-235 makes up less than one percent of the uranium in the world.Īlthough some of the uranium the United States uses is mined in this country, most is imported. However, the specific type of uranium used to produce nuclear energy, called U-235, is rare. Uranium is also a very common element, found in rocks all over the world. That's because uranium atoms split apart relatively easily. Nuclear Food: Uranium Uranium is the fuel most widely used to produce nuclear energy. Nations such as Lithuania, France, and Slovakia create almost all of their electricity from nuclear power plants. The United States has more than 100 reactors, although it creates most of its electricity from fossil fuels and hydroelectric energy. As of 2011, about 15 percent of the world's electricity is generated by nuclear power plants. Removing the rods will allow a stronger chain reaction and create more electricity. The more rods of nuclear poison that are present during the chain reaction, the slower and more controlled the reaction will be. Nuclear poisons are materials, such as a type of the element xenon, that absorb some of the fission products created by nuclear fission. Rods of material called nuclear poison can adjust how much electricity is produced. The turbines drive generators, or engines that create electricity. ![]() The steam turns turbines, or wheels turned by a flowing current. The cooling agent, heated by nuclear fission, produces steam. A cooling agent is usually water, but some nuclear reactors use liquid metal or molten salt. The heat created by nuclear fission warms the reactor's cooling agent. The energy released from this chain reaction creates heat. Fission products cause other uranium atoms to split, starting a chain reaction. As they split, the atoms release tiny particles called fission products. In a nuclear reactor, atoms of uranium are forced to break apart. The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium. A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity. In the process of nuclear fission, atoms are split to release that energy. In fact, the power that holds the nucleus together is officially called the " strong force." Nuclear energy can be used to create electricity, but it must first be released from the atom. There is a huge amount of energy in an atom's dense nucleus. Atoms are tiny units that make up all matter in the universe, and energy is what holds the nucleus together. Nuclear energy is the energy in the nucleus, or core, of an atom. ![]() Redi covered the tops of the first group of jars with fine gauze so that only air could get into it. Redi took six jars and divided them into two groups of three: In one experiment, in the first jar of each group, he put an unknown object in the second, a dead fish in the last, a raw chunk of veal. A modern rendering of Redi's experiment on abiogenesis At the time, prevailing wisdom was that maggots arose spontaneously from rotting meat. The book is one of the first steps in refuting " spontaneous generation"-a theory also known as Aristotelian abiogenesis. Redi is best known for his series of experiments, published in 1668 as Esperienze intorno alla generazione degl'insetti ( Experiments on the Generation of Insects), which is regarded as his masterpiece and a milestone in the history of modern science. Main article: Spontaneous generation Esperienze intorno alla generazione degl'insetti frontcover This work marked the beginning of experimental toxinology/ toxicology. He even showed that by applying a tight ligature before the wound, the passage of venom into the heart could be prevented. He performed a series of experiments on the effects of snakebites, and demonstrated that venom was poisonous only when it enters the bloodstream via a bite, and that the fang contains venom in the form of yellow fluid. He explained rather how snake venom is unrelated to the snake’s bite, an idea contrary to popular belief. In this he began to break the prevailing scientific myths (which he called "unmasking of the untruths") such as vipers drink wine and shatter glasses, their venom is poisonous if swallowed, the head of dead viper is an antidote, the viper's venom is produced from the gallbladder, and so on. In 1664 Redi wrote his first monumental work Osservazioni intorno alle vipere ( Observations on Vipers) to his friend Lorenzo Magalotti, secretary of the Accademia del Cimento. Scientific career Experimental toxicology Ī collection of his letters is held at the National Library of Medicine in Bethesda, Maryland. He died in his sleep on 1 March 1697 in Pisa and his remains were returned to Arezzo for interment. He was also a member of the Accademia del Cimento (Academy of Experiment) from 1657 to 1667. It is here that most of his academic works were achieved, which earned him membership in Accademia dei Lincei. Here he was registered at the Collegio Medico where he served at the Medici Court as both the head physician and superintendent of the ducal apothecary to Ferdinando II de' Medici, Grand Duke of Tuscany and his successor, Cosimo III. He constantly moved, to Rome, Naples, Bologna, Padua, and Venice, and finally settled in Florence in 1648. After schooling with the Jesuits, Francesco Redi attended the University of Pisa from where he obtained his doctoral degrees in medicine and philosophy in 1647, at the age of 21. His father was a renowned physician at Florence. The son of Gregorio Redi and Cecilia de Ghinci, Francesco Redi was born in Arezzo on 18 February 1626. A collection of his poems first published in 1685 Bacco in Toscana ( Bacchus in Tuscany) is considered among the finest works of 17th-century Italian poetry, and for which the Grand Duke Cosimo III gave him a medal of honor. He possibly originated the use of the control, the basis of experimental design in modern biology. He also distinguished earthworms from helminths (like tapeworms, flukes, and roundworms). ![]() He was also the first to recognize and correctly describe details of about 180 parasites, including Fasciola hepatica and Ascaris lumbricoides. He correctly observed that snake venoms were produced from the fangs, not the gallbladder, as was believed. He disproved that vipers drink wine and could break glasses, and that their venom was poisonous when ingested. His most famous experiments are described in his magnum opus Esperienze intorno alla generazione degl'insetti ( Experiments on the Generation of Insects), published in 1668. A rationalist of his time, he was a critic of verifiable myths, such as spontaneous generation. Having a doctoral degree in both medicine and philosophy from the University of Pisa at the age of 21, he worked in various cities of Italy. He was the first person to challenge the theory of spontaneous generation by demonstrating that maggots come from eggs of flies. ![]() He is referred to as the "founder of experimental biology", and as the "father of modern parasitology".
