# The Scale of the Universe 2

Irony punctuation Irony punctuation is any proposed form of notation used to denote irony or sarcasm in text. Written English lacks a standard way to mark irony, and several forms of punctuation have been proposed. Among the oldest and most frequently attested are the percontation point proposed by English printer Henry Denham in the 1580s, and the irony mark, used by Marcellin Jobard and French poet Alcanter de Brahm during the 19th century. Both marks take the form of a reversed question mark, "⸮". Irony punctuation is primarily used to indicate that a sentence should be understood at a second level. A bracketed exclamation point or question mark as well as scare quotes are also sometimes used to express irony or sarcasm.

Math Tricks This program is designed for those who want to learn interesting mathematical tricks to speed up the calculating. These tricks will help solve part of the mathematical problems and tasks much faster than classical. Will also be helpful to those who want to hone basics such as the multiplication table. Geometry of the Universe Can the Universe be finite in size? If so, what is ``outside'' the Universe? The answer to both these questions involves a discussion of the intrinsic geometry of the Universe. At this point it is important to remember the distinction between the curvature of space (negative, positive or flat) and the toplogy of the Universe (what is its shape = how is it connected). It is possible to different curvatures in different shapes.

Dark Energy, Dark Matter Dark Energy, Dark Matter In the early 1990s, one thing was fairly certain about the expansion of the Universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. 9 Hilariously Random Websites To Help You Procrastinate The Internet is a wonderful place, but sometimes it just spawns the weirdest creations.Case in point — these 9 websites. Some are genuinely hilarious for no good reason. Others are just so strange you’ll wonder why they were ever created. Regardless, you’re bound to have a laugh or two…while you procrastinate. Sanger.dk 12 'No Nose' GIFs That Will Delight and Horrify You Remember when Grandpa would steal your nose as a kid? For the children who didn't get their honkers back, there's a place for them on Internet. The subreddit r/nonose/ features hilariously horrifying photos and GIFs that, as the name suggests, have no noses.

Top 10 Math Websites for Elementary Students There are so many great websites out there for Elementary students that I decided to put together some Top 10 Lists for websites to use in the upcoming school year. For the next few weeks, I’ll be posting lists of sites to use for various subjects. Be sure to see the post I wrote about organizing websites, if you need a way to keep track of all of these. The Absurdity of Infinity: Astrophysicist Janna Levin Explains Whether the Universe Is Infinite or Finite in Letters to Her Mother – Brain Pickings By Maria Popova In 1998, while on the cusp of becoming one of the most significant theoretical cosmologists of our time, mathematician-turned-astrophysicist Janna Levin left her post at Berkeley and moved across the Atlantic for a prestigious position at Cambridge University. During the year and a half there, she had the time and space to contemplate the question that would eventually become the epicenter of her career — whether the universe is infinite or finite.

CoP - Using Astronomy as an aid to teaching STEM The idea for this CoP, simply called “Using Astronomy as an aid to teaching STEM”, came from many interactions with schools and their teachers and culminating in the inGenious astronomy chat that involved 35 schools from across Europe in December 2012. Astronomy is a great way to “package” ideas, and understanding the universe naturally requires teachers and students to ask questions that involve all the STEM subjects, and even some non-STEM subjects. This CoP will encourage teachers to look at new ways to present some old ideas, using the fast-changing face of astronomy to provide the context. Astronomy is found to be naturally fascinating by many students.

10 Websites Guaranteed To Press Your Buttons [Weird & Wonderful Web] We humans are naturally curious creatures. We see something, almost anything, and we want to reach out and grab it, touch it, feel it, and interact with it. Which is all good as long as the thing we’re reaching for isn’t going to bite us or trigger a nuclear holocaust. 40 Maps They Didn’t Teach You In School By the time we graduate high school, we learn that they never taught us the most interesting things in there. Sure, you might be able to name the European countries or point New York on the map, but does that give a you real understanding of how the world functions? To fill this gap, we have gathered a great and informative selection of infographical maps that they should’ve shown us at school: every single one of these maps reveals different fun and interesting facts, which can actually help you draw some pretty interesting conclusions.

First Grade Math Games Math games are a great way to engage kids in learning with all their senses. They give math practice that feels like play, and surround the learning process with fun, humor, and a nice dash of competitiveness. What's the Right Level? The right game will give kids practice, confidence, and the mastery of new skills. But how do you know if your game is appropriate for your child—not too easy and not too hard? The aliens are silent because they're dead Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU). In research aiming to understand how life might develop, the scientists realised new life would commonly die out due to runaway heating or cooling on their fledgling planets. "The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens," said Dr Aditya Chopra from the ANU Research School of Earth Sciences and lead author on the paper, which is published in Astrobiology. "Early life is fragile, so we believe it rarely evolves quickly enough to survive." "Most early planetary environments are unstable. To produce a habitable planet, life forms need to regulate greenhouse gases such as water and carbon dioxide to keep surface temperatures stable."

Kepler: Educator Web Links Educator Web Links Oct 2011: Agent Exoplanet—Astronomers at Las Cumbres Observatory are investigating exoplanets and you can too. Through Agent Exoplanet you use images taken by Las Cumbres Observatory Global Telescope Network (LCOGT), measure the brightness of a star while a planet moves between it and our viewpoint (exoplanet transit event), and contribute to understanding the properties of each exoplanet.

I'd seen the Morgan Freeman version before, but not the 1977 one. Remarkable how we're still only theorising about what's beyond the sub-nuclear level! by Nov 4
