Some foods have significantly more Calories than others but what does the difference actually look like. Each of the photographs below represents 200 Calories of the particular type of food; the images are sorted from low to high calorie density.

In other words, you have a fixed amount of Calories to “spend” each day; based on the following pictures, which would you eat?

“The Lockheed SR-71 “Blackbird” was an advanced, long-range, Mach 3+ strategic reconnaissance aircraft. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by the Lockheed Skunk Works. Clarence “Kelly” Johnson was responsible for many of the design's innovative concepts. During reconnaissance missions the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outrun the missile”. – Wikipedia

These stunning images reveal the remains of a more than century-old sunken ship that has been preserved beneath freezing Lake Superior. The ship looks almost exactly the same as it did the day it sunk beneath waves all those years ago. At 60 meters long (approximately 198 feet), the «Gunilda» sunk after it struck some rocks and was not saved. Now, these stunning images have been captured 107 years after the sinking when a small group of divers revisited the vessel. (Photo by Becky Kagan Schott/Caters News Agency)

Computer Inc. (Asus) unveiled the Zenbook, the new super-thin laptops. Encased in brushed steel, the Zenbook feels solid, yet light. “The super-thin laptop’s $999 configuration, which includes 4 GB of 133MHz DDR 3 RAM, a 128 GB SATA Solid State Drive (SSD) and two USB 3.0 ports, is $200 cheaper than a similarly configured “competitor” (read: MacBook Air). You can by a MacBook Air for $999 with the same Intel Core i5 CPU — but with only half the memory and storage space. Zenbook would get 7 hours of battery life (roughly 3.4 hours of streaming video and 3.25 hours of gameplay) and could remain in standby for up to two weeks”.
