An Introduction to Photoshop Compositing for Beginners - Digital Photography School by Sarah Hipwell What is compositing? Simply, it means to combine two or more images to make a single picture. danielrapp.github Recently I stumbled upon an interesting paper for implementing motion sensing requiring no special hardware, only a speaker and mic! Unfortunately the paper didn't include code to test it, so I decided to reproduce it here on the web! What is the doppler effect? First of all, what is the doppler effect? Total lunar eclipse of September 28, 2015 - online broadcasts schedule After more than 30 years a supermoon in combination with a lunar eclipse will be visible again across the skies of North and South America, Europe, Africa and parts of west Asia and the eastern Pacific. This rare celestial event is set for September 28 (UTC), 2015, and is expected to last for 1 hour and 11 minutes. For those who might find themselves to be unlucky with their location, weather conditions or light-polluted night skies, there is still hope, as many observatories will broadcast the event - live and free: NASA will broadcast the event from 00:00 UTC until at least 03:30 UTC, September 28, from Marshall Space Flight Center in Huntsville with a live feed from the Griffith Observatory, Los Angeles, Adler Planetarium, Chicago, Fernbank Observatory in Atlanta and other locations across the US. Slooh Community Observatory will broadcast the event starting 00:00 UTC on September 28 with a live feed from Canary Islands, Spain. Video credit: ScienceAtNASA
Pysics is Phun! Enter the wild world of physics where appearances and logic are often turned upside down. Understanding the underlying concepts is essential for uncovering the magic of physics. It can be a thrilling adventure for students as they discover lots of cool methods for lasting knowledge. Five Visualizations to Grasp the Scale of the Universe by Maria Popova What coffee beans, dinosaurs and lakeside picnics have to do with Isaac Asimov and formalized figments. Since yesterday was 10.10.10, we’ve decided to celebrate this cosmic alignment of numerical symmetry by illuminating the measurements of magnitude. Today, we are taking five different looks at one of the most difficult concepts for the human brain to quantify and understand: The size and scale of the universe.
Introduction to the Photoshop Toolbar (Part 1) In this article (Part 1 of 3) I will give you a quick introduction to the Photoshop CS5 toolbar. The toolbar is a floating panel normally placed at the left of the screen. View Other Articles in This Series Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy.
Yale researchers seek explananation for abnormal star light Invisible to the naked eye, light peculiarities emanating from a distant star — KIC 8462852 — grabbed the attention of amateur and professional astronomers alike when they viewed the abnormalities through NASA telescopes four years ago. The abnormal phenomenon and its possible causes have recently been thrust into the spotlight once again due to a new Yale study determining that the phenomenon was most likely caused by a swarm of comet fragments. Over 1,400 light years away from the Earth, KIC 8462852 has exhibited extreme fluctuation in its light output over the past four years. Amateur astronomers from a citizen science project called Planet Hunters first spotted this anomaly while combing through public data collected by the NASA Kepler spacecraft. Planet Hunters was established in 2010 with the help of Debra Fischer, an extrasolar planet hunter and astronomy professor at Yale. “The comet scenario was our best [explanation],” Boyajian said.
