![]() Detectors improved and new wavebands opened up, but mass, flexure and thermal inertia proved serious obstacles to larger mirrors.Ī mirror needs to be stiff enough to hold its shape against the wind and (at least in the mid-20 th-century paradigm) against its own weight. device in the 1930s and its commissioning in 1948 after the war, growth in telescopes was put on pause for almost half a century. Following the construction of the 200-in. A brief history of telescopesĪ previous burst of telescope development occurred during the early 20 th century, when George Ellery Hale led efforts that culminated in the 60-in. Direct imaging will one day lead to spectroscopy and the ability to detect oxygen in a planet’s atmosphere, the signature of life. The new generation of telescopes, including the GMT, will be able to image mature planets down to about Jupiter’s size, with orbits as small as Earth’s, as well as smaller Earth-like planets that are young enough to glow in the infrared as their gravitational energy leaks out. ![]() Just last year, astronomers reported the first images of several large planets orbiting other stars-planets several times larger than Jupiter with orbits similar to those of Uranus, Neptune and Pluto. Several hundred extrasolar planets have been detected by their star’s tiny oscillation around the common center of mass, or the slight darkening that appears when they pass in front of the star.ĭirect imaging is much more difficult because the planet is so close to the billion-times-brighter star. One quest that demands all of the sensitivity and resolution that can be squeezed out of a telescope is the direct imaging of planets around other stars. Sensitivity scales with area, and resolving power scales with diameter if a coherent wavefront can be maintained. With their unprecedented sensitivity and angular resolution, these telescopes open new windows onto the universe. And slight distortions in the images of distant galaxies can map the distribution of the invisible dark matter that appears to make up over 80 percent of the universe’s mass. A large telescope can capture supernovae (catastrophic explosions of stars that have run out of nuclear fuel) at such great distances that scientists can use the images to trace the expansion and acceleration of the universe. In others, they will study objects to reveal the fundamental structure and evolution of the universe as a whole. In some cases, their goal is to understand the structure and evolution of the objects themselves. Astronomers will use them to study distant planets, stars, galaxies and black holes. The GMT is part of a wave of new, ever-larger telescopes that first came on the astronomical scene in the early 1990s. Today, it’s a piece of the test optic system that is guiding the manufacture of the 25-m primary mirror for the Giant Magellan Telescope (GMT). Twenty years earlier, this mirror could have become the primary mirror for the sixth largest optical telescope in the world. ![]() ![]() In August 2006, the Steward Observatory Mirror Lab cast a 3.75-m mirror under the stands of the University of Arizona football stadium. The seven primary mirror segments form a single 25-m parent surface, while the seven matching secondary mirror segments form a 3.2-m concave surface. Artist’s concept of the Giant Magellan Telescope.

![]() My son received this for Christmas and it was Instantly one of his favourite gifts! Lots of fun to play, even with the noisy motor and suspect score keeping. The pinball machine stopped working after two days Requires 3 x AA batteries (not included). Everyone can take turns trying to set a new high score! For 1 or more players. This fully automated pinball set detects when the ball falls into the drain & and keeps track of your high scores. This pinball machine has made no compromises on functions - the bumpers actually vibrate as the ball comes into contact with them, giving a true pinball sensation! Colourful LED lights on both sides of the machine light up as you score points and reach certain milestones, and sound effects enhance the excitement. ![]() ![]() While arcade soundtrack music plays in the background, the giant electronic scoreboard keeps track of your points.

WEEK 7 CURRENTLY IS TIMED EXCLUSIVE TO NEWGROUNDS.COM ![]() It’s a lifesaver for myself and Amanda when we’re localising stories, or fixing my own fuck-ups, and it’s something I wish Chrome would just let users enable by default. Chrome only spell-checks the lines around the cursor, rather than the entirety of a text box as soon as it’s active: I can see the efficiency argument here from Google: if a user hasn’t clicked on a text box, why waste resources on grammar and spell checks until it’s needed? That said, if you’re typing for a living – and many of us do, even if you’re not in the world of professional publishing – being able to quickly parse the errors of a document is super handy.Again, not the most secure option, but bloody handy. Firefox doesn’t have that problem, and you can access your saved logins which can be a lifesaver in a pinch. But sometimes I need to login to an app or browser quickly, and for whatever reason – probably enforced by the developers – Chrome never actually remembers the login details. Firefox actually saves passwords: I can hear people groaning in the background already at the security implications of this – and yes, I do use separate password managers personally and professionally.It’s neck and neck for practical purposes, which brings the other major benefits of Firefox into play: I’ve run some eyeball tests this morning, and while Chrome pops up a fraction of a second faster, that’s all it is. The early Firefox Quantum betas were much better than the Firefox of old – but our work sites still loaded up faster (without adblock, to be clear), which was one of the major reasons I switched back. The main things I was looking for were all productivity based: I wanted something that was memory efficient, especially when I’ve got multiple browser tabs competing for memory space with Photoshop, occasionally Open Broadcaster Software (if recording) and other apps. Gaming in a browser, even as someone who runs a gaming site for their day job, isn’t close to the main reason I switched browsers though. support for two players, on a single screen. But one of the projects has got a nice ace up its sleeve. We've talked about some of the Tomb Raider fan remakes before, and some of them are pretty cool. ![]() ![]() Fan-Made Tomb Raider Remake Adds Multiplayer Using 3D Glasses No, the significance of the K-horn is that the product has remained in production and quite popular and thought very highly of by many for more than 60 years since it was originally introduced, with only relatively minor changes to the design being made since its original introduction. Roy Allison's company once marketed the Allison 3, a speaker meant to be placed in a corner, but it was not a horn at all. Another vintage monster speaker (with a 30-inch woofer), the Electrovoice Patrician, was recommended for corner placement, but was not a horn-loaded woofer and could work well anywhere in the room. The Avant Garde Trio uses a bass horn, but is not meant to be corner loaded neither was the company's later Bass Horn. Most horn-loaded speakers today are not meant to be corner loaded and few use bass horns at all. The K-horn got the corner horn part right, I think, but, to my knowledge, not too many have followed that path. Corner horn designs are few and far between. I don't believe the Klipschorn is really representative of any significant trend in home or even pro audio. That's what I would expect for a speaker which so polarizes opinions. As I said in the first paragraph of my post which started that thread: " K-horns are controversial and opinions not only vary widely, but are usually extremely polarized: listeners seem to either love 'em or hate 'em." The K-horn made exactly four out of eight of the top-12 lists of the polled TAS reviewers. My own review if this speaker is the subject of a separate thread here. I've been around audio long enough to have heard many of these at some length and over a number of years in different venues. I thought it would be fun to comment not only on the current significance of the trend represented by each speaker, but also on the speaker's sound itself, if I'm familiar with it. Here are my takes on the list compiled from the eight reviewers' recommendations, starting from the bottom up. Or, in a few cases, designs which have stood the test of time extraordinarily well. No, the attempt was to name trend setters, designs which set the stage for later designs which built on the originals, or which inspired other designers to greater heights. ![]() It is clear from reading the article that few, if any, of the reviewers were naming speakers which the necessarily believe are the best sounding of all time, although there are probably a few of those among the nominees. In it, eight current reviewers of TAS, including founder Harry Pearson, were asked to name the dozen speakers which they thought to be the 12 most significant loudspeakers of all time. This is the title of a fascinating article in the current September 2010 Issue 205 of The Absolute Sound. ![]() You can use macOS Ventura on your Mac or Windows PC as long as you have virtualization software installed, such as VirtualBox or VMware.
