WEIGH IN ON iD This issue’s cover is experimental. We are exploring the merits of an update to iD’s traditional image, and we would very much like to hear your opinions on that before anyone makes any lasting moves. So at right are two covers; some readers saw the traditional cover on the left with the regular iD logo and others saw the alternate cover on the right with the modified logo. Which logo looks more appealing to you? Please send us an email at questions@ideasanddiscoveries.com and let us know! BANDWIDTH ON WHEELS When I read the Photo & Story in the March issue regarding the Amazon Web Services data transfer solution vehicle, it reminded me so much of a great and appropriate quote from the noteworthy computer scientist Andrew S. Tanenbaum: “Never…

what secret ingredient makes a wall great?

Portions of the Great Wall of China, some of which is well over 2,000 years old, are still in remarkably good shape. The material that keeps the wall standing after more than two millennia is a surprising one: rice. The ingredients in the mortar are lime, water—and sticky rice. Amylopectin, an organic component of the rice, combines with the lime to produce a material that is strong and stable enough to resist an earthquake. The mortar’s bond with the brick is so strong in some places that it has prevented weeds from growing between the bricks. Modern-day archeologists still use a similar mortar when they’re making repairs to the Great Wall. 4,000 miles is the traditional length of the Great Wall of China, but in 2012 the Chinese government released a…

love is in the air dating and mating in the animal kingdom

In hot pursuit of a family affair Affection prevails among the cuddly prairie dogs, which are ground squirrels that live in the grasslands of North America—or more precisely, under the grasslands. The stout herbivores dig elaborate burrows below the ground surface where numerous families can reside. These “towns” are vital to the well-being of the community, because prairie dogs are extremely social creatures. They’re also awake all throughout the long winter, like their cousins the tree squirrels, which also do not hibernate. And what’s a mammal to do to while away the hours till spring? For even with many conspecifics around, it can be hard to meet your match. For prairie dogs, it’s a numbers game: The more mates, the more offspring, as nothing makes for a large family like multiple…

the biggest taboos of world history

MONOTHEISM: Did Tutankhamun really exist? MISSING NUCLEAR WEAPONS: How many atomic bombs has America lost? WAR CRIMES: Were the Allies really just liberators? PLANNED PUTSCH: Did West Germany’s Federal Intelligence Service want to overthrow the government? ANTI-SEMITISM: Was the “Final Solution” Martin Luther’s idea? You have to know history in order to truly understand the present time. Historians like to utilize that phrase to emphasize just how important it is to know what happened in the past. We tend to believe that all of the most significant events have been explored from every possible angle—reviewed and verified a hundred times or more. That might be true for 99% of history. But even to this day mysteries remain, either because a given event has been off-limits to historians or because the circumstances have been deliberately misconstrued.…

could you stay alive alone in the wild?

America is a rich natural paradise: from the Appalachian Mountains in the east to the Sierra Nevadas in the west, from the bayous of Louisiana to Minnesota’s 10,000 lakes, from the desert plains of New Mexico and Arizona to the ice fields of Montana. As more and more Americans take to the outdoors, even in the modern era of GPS smartphone navigation, it’s not a bad idea to acquire some elementary knowledge and essential facts about surviving outdoors in an emergency. Perhaps your car breaks down in a remote area, or you get separated from your hiking group, or you lose your way in the woods: In a wide variety of situations, you may find that your very survival suddenly depends on taking advantage of the limited resources available to…

how do you build a floating wind farm?

80 WIND TURBINES …have been in almost constant motion since 2002 at the North Sea’s first big wind farm at Horns Rev 1, about 10 miles off the west coast of Denmark. Total capacity: 94.8 MW. The hub of each wind turbine is 230 feet high and the rotor diameter is 262 feet. 13 FEET PER SECOND …is the minimum wind speed required to turn the rotors. That plus high humidity, with a layer of moist warm air hovering over the North Sea and a layer of colder air above the warm one, create the conditions seen here. The wind turbines stir up the two layers and the moisture in the warm air condenses in the colder air above, creating visible streams of fog. 290 FEET PER SECOND …is the rotor blades’ top speed in…
