10 Educational Facts You Probably Don't Know
It’s the weekend. That means it’s time to relax, unwind, and learn something. In that vein, I thought it might be fun to recap one of my favorite posts of all time from Buzzfeed. They compiled a lengthy list of facts that will ‘blow your mind’ and I wanted to share both the post and some of my favorites. What follows are 10 factoids that I didn’t know but feel a teensy bit smarter for now knowing. The “YKK” on your zipper stands for “Yoshida Kogyo Kabushikigaisha:” 3.14 is PIE backwards: Cashews grow like this: Pineapples grow like this: Here’s what velcro looks like close up: Here’s what chalk looks like under a microscope: Here’s what sand looks like under a microscope: A Blue Whale’s heart is so big, a small child can swim through the veins: There’s enough water in Lake Superior to cover all of North and South America in one foot of water:
The Evolution Of School Supplies
School has been around for a couple thousand years, give or take, and thus, in some form or another, so has an incarnation of what we now call the “Back to School season”. Now, students and their parents flock to stores with credit cards at the ready, prepared to purchase all the trimmings of a successful school year. Carts are filled with new clothes, sneakers, notebooks, pens and pencils, and other accoutrements. As they purchase these items for their kids, many parents reflect what was different when they were returning to school as children. Take a look at this handy infographic from Red Leaf Loans and see how our school supplies have evolved over time.
The World’s Most Powerful Digital Camera Snaps Its First Photos
On a mountaintop in Chile is the most powerful digital camera mankind has ever constructed. Called the Dark Energy Camera, the phone booth-sized device shoots 570-megapixel photographs using an array of 62 separate CCD sensors and a 13-foot light-gathering mirror. Planning and building the thing took 120 scientists from 23 international organizations a whopping 8 years. This past week, the researchers behind the project announced the first fruits of their labor: massive photographs that show patches of the sky 20 times the size of the moon (as seen from Earth). The photographs are so big and so sensitive that each one shows over 100,000 separate galaxies that are up to 8 billion light years away. Over the next five years, scientists plan to create these massive color photos of 1/8th of the night sky, capturing 300 million galaxies, 100,000 galaxy clusters, and even 4,000 supernovae.

Through the clouds – Amazing Sun Rays Photography
digg Sun Rays Photography is definitely one of the most inspiring and vivid. Being the simple natural phenomenon that we observe every day, it brings hope and warmth in our hearts. Even when the dark clouds swaddle all the sky, there is always a tiny sun ray that strikes its way through all this mess. Undoubtedly, everything that is connected with sun is rather difficult to capture but enormous efforts that should be made in order to create perfect shot is justified, since this kind of photography is absolutely brilliant. Today, I have collected 30 examples of amazing sun rays photography. If I have missed something let me know via comment section at the end of the post.

Investigators look past horror to help children
Jennifer Aglialoro didn't mind that the little girl hid behind the couch, her face shrouded in her hood. She just wanted her to keep talking and, with any luck, the abuse the child suffered would come up in the conversation. "It's one of those kids I'll never forget because I helped her say it. She wasn't going to say it, and she came here, and we helped her say it," Ms. Aglialoro said. Hearing those stories about children being beaten, raped or molested would be unendurable for most. But Ms. "If my child said that to me I'd be horrified and I'd be upset," Ms. Every day, Ms. "I learned a long time ago that if I'm here or not it's going to happen," Ms. In a nondescript room on Mulberry Street filled with little more than a couch, a couple of beanbag chairs and a camera, they sit down with children one-on-one and hope they will open up and tell them about what are likely the worst moments of their young lives. "It's very precise. Ms. "So you never really focus on 'this is why we're here.'
Where is Technology Leading Higher Education?
Culture Digital Tools Teaching Strategies By Doug Ward The rush to create large, free online classes has generated anxiety at universities around the country. With finances already tight and with a surge of movement toward online learning, universities are being forced to move quickly to change centuries-old models of learning. Terms like historic, seismic and revolutionary now pop up in descriptions of the challenges that higher education faces in the coming years. Many institutions have been preparing for these changes for years, building infrastructure and expertise, experimenting and recruiting, and integrating online learning into long-term strategies. This point of dramatic — and traumatic — change didn’t swoop in unannounced. Internet connections, computers and cellphones have become faster and cheaper, providing easier access to online material and creating the potential to speak with, work with, and learn from nearly anyone in the world. It’s also changing the way they learn. This
