How Pluto's most spectacular image was made—and nearly lost By the end of the day on 14 July, the stunning picture of Pluto above would become iconic—the most “liked” image ever on NASA’s Instagram account. Even U.S. President Barack Obama would tweet it out. But the night before, at 11:07 p.m. Hal Weaver, the project scientist for New Horizons, watched the data packets accumulate one by one on the server, and waited for an automated process to collate them into a FITS file—a rudimentary image. Assembled there were the five scientists appointed earlier in the day to toil through the night sprucing up the image. Parker took the thumb drive from Weaver, who then left the room. But Weaver couldn’t find the right file. At 12:40 a.m., Weaver called the Union into his office, where he brought the image up on his Apple Thunderbolt display. NASA’s New Horizons team reacts to the first full-frame images of Pluto shown at a 6 a.m. science team meeting on Tuesday, 14 July. Howett’s eyes were first drawn to the icy “heart” in the middle of the image.
Super Teacher Tools If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
Watch the digital landscape evolve through these stunning short films | Motion graphics This year marks a milestone for OFFF Barcelona. It's the 15th anniversary of the epic three-day design conference, and plans are in place to make it a party to remember. Over the past 15 years the crew have invited some of the industry's most exciting creative names – new and established – to create the main titles for the three-day design fiesta: Gmunk, Joshua Davis, Julien Vallee, The Mill, Postpanic, the list goes on… Subscription offer A lot's changed in the last decade and a half. Like a 15-year timelapse, the titles make for fascinating viewing, charting the rise and fall of Flash and capturing moments of motion brilliance crafted around the world. We've collected some of the most interesting ones here for you to look back through… 2014: The Mill Creative director Ash Thorp joined forces with musician and filmmaker Anthony Scott Burns to transform OFFF Barcelona's main titles into a stunning short film, and it was a bumper year for OFFF on Tour. 2013: From Form 2010: Julien Vallée
How Big Is The Brain? Here's Some Perspective. SExpand Imagine your brain is the size of Earth. How big would all of its constituent parts be? The brain-mapping folks at Eyewire teamed up with Visual.ly and FEI to host a Scale-Of-The-Brain infographic competition. With competition judges like Christopher Jobson (of Colossal), Maria Popova (of Brainpickings) and MIT neuroscientist and professional brain-mapper Sebastian Seung, entries neede to be not only visually appealing but scientifically accurate. While not wrong, this statistic annoys me. H/t Amy Robinson The Ultimate Directory Of Free Image Sources - The Edublogger So, you need an image for your blog? We’ve spent some time categorizing our favorite sources for free images and organizing them in such a way as to help you find what you’re looking for. Here are the criteria we’ve examined: Subjects: Does a site focus on specific genres of images, or is it a mass collection of various image types? High Resolution: Lots of great image resources emerged in the pre-Web 2.0 phase, but it wasn’t until bandwidth dramatically increased that allowed for the uploading of much higher resolution images suitable for editing and printing. License: The licenses vary extremely from source to source. Safety: Government sites and many specific subject collections are extremely safe for students to use. Search Engines While these websites do not actually contribute image content themselves, they’re able to index images in a way that makes it easier to search for free content.

Simplex, ou comment les maths nous simplifient la vie ! Développer la culture mathématique chez les plus jeunes et comprendre par le jeu que l’on peut agir grâce aux maths ! Tel est l'objectif de la série d'animation Simplex. Chaque épisode est dédié à un théorème mathématique et prend la forme d’une situation-problème concrète, réaliste, connectée au quotidien des adolescents. L'histoire : dans la ville de Simplex, 4 adolescents, Ines, Marion, Tom et Julien, réussissent avec l’aide d’Euler Evariste, un videur de boîte de nuit érudit mais taciturne, à mettre en pratique les mathématiques dans leur vie quotidienne. Leur secret ?
Why Do Rivers Curve? - A Video and a Game Why Do Rivers Curve? is a short video produced by Minute Earth. The video explains and demonstrates the role of erosion in forming the bends in a river until an oxbow lake is formed. The video concludes with a challenge to use Google Earth to locate an oxbox lake. VIDÉO : 13,8 milliards d’années d’évolution cosmique en 2 minutes Une nouvelle simulation numérique permet de reproduire avec une précision inédite l’évolution de la matière et la formation des galaxies durant plus de 13 milliards d’années au sein d’un cube de 350 millions d’années-lumière de côté. © Illustris Collaboration/ Illustris Simulation/Le Monde Ne pouvant réaliser aucune expérience pratique avec des étoiles ou des galaxies, les astrophysiciens tentent d’expliquer leurs observations ou de conforter leurs hypothèses en créant des simulations numériques. Tributaires de leur compréhension initiale des phénomènes physiques impliqués, des moyens mathématiques à leur disposition pour les modéliser et de la puissance de calcul des ordinateurs, les chercheurs peuvent profiter de l’amélioration constante de ce dernier point pour raffiner régulièrement les paramètres de leurs simulations et pour tenter d’approcher un peu plus la réalité. © Mark Vogelsberger et al.

Matériels innovants 1/ Le Thamographe Voilà l’outil mystérieux: Il peut remplacer la règle, l’équerre et le compas (et même le rapporteur !). Il mérite d’être testé et peut être une aide intéressante pour certains élèves. Sur le site : Vous pourrez le commander, voir des vidéos et télécharger des supports pédagogiques. Certains n’y arrivent pas. 2/ L’ Eker Eric Kermovant, Formateur en mathématiques à l’ESPE de Saint Brieuc a inventé l’Eker pour aider les élèves à tracer les angles droits. L’Eker est un simple L de deux côtés égaux de 13 cm de long, qui permet toujours de tracer un angle à partir de l’extérieur de l’équerre, mais surtout de l’intérieur,ce qui permet d’être bien plus précis. En savoir plus: article Ouest France L’acheter : lien 3/ La kangourègle Voilà un EXCELLENT outil : La Kangourègle permet de : – mesurer des segments, – tracer des segments de mesure donnée – tracer le milieu d’un segment – tracer des parallèles – tracer des perpendiculaires – tracer des angles à 30°, 45°, 60°
Science experiment on soil erosion This post is also available in: Italiano Science experiment on soil erosion – This experiment, which has a tremendous visual impact due to its simplicity, it will demonstrate the relationship between precipitation, soil erosion, protection of watercourses and vegetation. A very simple experiment that stresses the importance of the vegetation cover of the soil. You can propose in three versions: – Preparing the planting of seedlings – Using plants ready to be transplanted – Using soil samples. Science experiment on soil erosion – First version Prepare three identical plastic bottles, cut as shown in the pictures and put them on a flat surface (I’ve stuck with the hot glue on a tablet of plywood): the opening of the three bottles should protrude a little out of the surface. Cut the bottom of other three bottles of transparent plastic, and make two holes for the string. Then put the cap on the first bottle in which to plant the seeds: Here are the pictures taken two weeks after sowing:
