50 Fascinating Pictures That Let The Human Body Explain The True Size Of Things
When you read about something or see it on TV, the (lack of) context might leave you guessing — or even worse, misinterpreting — the details.
Luckily, r/HumanForScale solves that problem. Every picture on the subreddit comes with a body or two so that we, the viewers, can accurately gauge the dimensions of objects, whether they're wild animals, historical artefacts, or architectural wonders.
In a world where everyone wants your attention and misinformation spreads faster than ever, clarity is queen.

Clydesdales are very large, but I also think she's probably not very tall.

Susana Martinez-Conde and Stephen L. Macknik are both professors of ophthalmology, neurology, and physiology & pharmacology at SUNY Downstate Health Sciences University in Brooklyn, New York. They say that absolute size is meaningless to our brain.
"We gauge size by context," Martinez-Conde and Macknik, authors of Champions of Illusion, wrote. "The same medium-sized circle will appear smaller when surrounded by large circles and bigger when surrounded by tiny ones, a phenomenon discovered by German psychologist Hermann Ebbinghaus."
"Social and psychological context also causes us to misperceive size. Recent research shows that spiders appear larger to people who suffer from arachnophobia than to those who are unafraid of bugs and that men holding weapons seem taller and stronger than men who are holding tools."

Neuroscientists from the University of Washington and the University of Minnesota have even found that the first area in the cortex of the human brain that receives information from the eyes processes the perceived size, rather than the actual size, of an object.
"Our eyes only tell us part of what we need to be able to see. The other part is done by the brain, taking the input from the eyes and making guesses or inferences about what's out there in the environment," said Scott Murray, who at the time was a UW assistant psychology professor and lead author of the study. "Usually these inferences are very accurate, but sometimes they lead us astray in the form of visual illusions."

Made This Yesterday. The Black Dot On The Stem Is Me
Took me longer than I care to admit, to realize that this was drawn in the snow and not on a giant white wall.
Murray and his Minnesota colleagues, Huseyin Boyaci and Daniel Kersten, used functional magnetic resonance imaging (fMRI) to see how the brain processes the size of objects when faced with an illusion such as the long-known moon illusion. (For centuries, it has been known that the moon, while rising, looks huge when it is near the horizon and smaller when high in the sky, even though it's always the same size.)
The researchers used a similar illusion, one that looked at the perceived difference in the size of an object at different distances. For their experiment, they placed two identical spheres decorated with a checkerboard pattern in the front and rear of a receding brick hallway. In this kind of illusion, the more distant object appears to occupy a larger portion of the visual field.

Using fMRI, the researchers analyzed how the brains of five people with normal vision registered this difference in perceived size. They noticed that the brain region known as the primary visual cortex, which is the first area in the cortex to receive input from the retina, showed a difference.
Even though both spheres occupied exactly the same size on the retina, the sphere in the rear activated an approximately 20 percent larger area in the primary visual cortex than the sphere in front. This difference closely matched a perceptual difference in size reported by the subjects. When they were asked about the size of the two spheres, the participants estimated the back sphere to be about 20 percent larger than the front one.

Murray said the simplicity of the outcome can be deceiving. "It almost seems like a first grader could have predicted the result. But virtually no vision or neuroscientist would have," he explained.
"The very dominant view is that the image of an object in the primary visual cortex is just a precise reflection of the image on the retina. I'm sure if one were to poll scientists, 99 percent of them would say the 'large' moon and the 'small' moon occupy the same amount of space in the primary visual cortex, assuming they haven't read our paper!"

When they were built, most everything was significantly cheaper in part because the infrastructure that served them was quite new. As they aged the required upkeep became expensive (anyone who has a utility bill knows) with added fees for maintenance of the utility systems and the buildings alike. Retrofitting them to make it cheaper to operate is as costly or moreso than a replacement building that is designed to accommodate and protect the contents within it.

Wind Turbine Maintenance
My brain can't work out what is happening with the thing on the right in this image
The thing on the right is one blade of the turbine. Two are fitted. Presumably, the ring of "sticky out things" are threaded studs/bolts which attach the blade to the turbine hub. I'd guess that the encrustation visible on the detached blade is snow or ice, looking at the landscape below. The standing structure looks new, so I'd guess that the blade is being moved into position for installation.
Load More Replies...There''s a plant in a free zone not far from where I live where the blades are manufactured. They are HUGE. When an order is shipped, it's one set of blades per flatbed truck and there usually are numerous trucks. The road has to be closed and the convey accompanied by a police escort.
Janissary35680: what you're seeing are relatively small blades. With the big blades, it's one per truck. I've just checked the specs for one modern big wind turbine - rotor diameter 175m (574 ft). Assuming 10m for the hub diameter (a guess), that means each blade is about 82.5 m (271 ft) long. Trucking them along ordinary roads is not at all easy. Here's a video of a 57.5m blade being taken along a road in Scotland: https://www.youtube.com/watch?v=iTpZ5V4HrK4.

The Evolution Of Jet Airliner Engine Sizes, From The Douglas Dc8 To The Boeing 777
I always liked this picture, of a 777's engine next to a 737 fuselage, and engine. Clipboard0...631079.jpg
It's not just size of the engine. The inner engine, core engine, hasn't grown nearly as much, but the more modern ones are Turbofan engines, having a huge fan in the front (basically, a propeller in a housing with as many blades as fit), that usually is about twice the diameter of the cor engine's compressor wheels and aims at increasing efficiency. The air flows around the inner engine, creates additional thrust, but isn't involved in combustion, that only happens in the inner engine. Core engine. Without this shift in technology in mind, the size comparison may be misleading, as the growth in diameter is real, no doubt, but it isn't the size of equivalent parts that has grown that far.
