- Exploring the defining steps in the history of our evolution.
- In the Summer of 1940 Britain stood alone on the edge of Europe. With Britain's shores secure, the Germans were left with one option. The Battle of Britain was the world's first war to take place entirely in the skies.
- Nothing screams technology like the hottest aircraft in the sky. Real Engineering explains how these aircraft and other modern contrivances work.
- The Logistic of D-Day covers the engineering and tactical advantages the Allies used to achieve victory when invading German-occupied France.
- NASA's AD-1 scissor wing experimental airplane incorporated a single rotating swept wing with a pivot at the top of the fuselage. The swept configuration allowed the plane to take maximum advantage of the Whitcomb Area Rule. But the advantages were outweighed by challenges with aerodynamic stability.
- In the metal 3D printing process lasers essentially weld metallic powder into a mechanical part. The process permits the creation of parts, particularly hollow parts, that would otherwise have to be assembled from multiple parts. But, as of now it's not a manufacturing ready technology because the parts suffer from metal fatigue and scale up requires the purchase of more machines rather than just raw materials.
- To exploit the D-Day landings and advance into the continent the allies required massive quantities of vehicles, equipment, munitions, fuel and supplies. The allies did not believe they could rely solely on beach landings to off load this materiel until a deep water port could be captured. So they determined to build their own deep water harbor off the coast of the Normandy beaches within a week or two after D-day.
- Space elevators dwell in the realm between science fiction and the science of possibility. The concept has been studied enough to understand the basic design and construction concepts. But it would require a very strong yet light weight cable. Carbon composites are now (2021) the best available candidate but the economics are doubtful. And that is just one of the engineering challenges.
- The Boeing 787 Dreamliner has a host of technological aircraft and engine technologies the substantially reduce weight and increase fuel efficiency enabling it to fly over 16,000 miles non-stop from Tahiti to Paris. The focus here is on the GE engine which is substantially more efficient, less polluting and quieter than any over engine in production.
- 5G cellphone transmission uses a portion of the electromagnetic spectrum that is troublesome for data transmission because something as common as rain will interfere with it. Here is an explanation of how it differs from the previsions generations and what is being done so it will work.
- Here is a detailed description of how to operate the Javelin anti tank missile is operated and how it penetrates the latest tank defenses.
- Becoming upright was one of the first milestones in becoming human. By freeing up our hands, a whole world of tool use, dexterity, and walking became available to us. It may have also allowed our ancestors' brains to grow. What does the fossil record tell us about how bipedalism first evolved?
- Once our ancestors gained the ability to walk upright, suddenly, their hands were free. Free to fist fight, carry things, and most importantly, create tools. The ability to manipulate the environment using external objects isn't entirely unique to our species, but we've taken it much, much further than any other creature. And the fossil record shows us that the evolutionary journey our ancestors took to create the first tools is an incredible one - one that paved the way to the tool-filled world we live in today.
- Once the hands of our ancestors became free, running became a part of our locomotion. Many animals are fast, but humans are the planet's best long-distance runners. How is this possible for such a strange gangly ape? The answer lies all over our bodies, in tiny pores unique to us - sweat glands.
- Today, humans are (probably) the only species with complex language. Did our hominin ancestors have the same ability? Was the evolution of language gradual in our species, or was it a sudden explosion of ability in a short period of time?
