Solving a long-standing problem in transmission electron microscopy
For researchers wanting to understand the inner workings of magnetic materials, transmission electron microscopy is an indispensable tool. Because the wavelength of an electron is much shorter than the wavelength of visible light, a beam of electrons transmitted through a thin slice of a material can create an image in which the inner structure of the material is magnified up to 50 million times, many orders of magnitude more than with an optical microscope.

Superlensing without a super lens: Physicists boost microscopes beyond limits
Ever since Antonie van Leeuwenhoek discovered the world of bacteria through a microscope in the late seventeenth century, humans have tried to look deeper into the world of the infinitesimally small.

Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary research team in the journal Nature Photonics. The researchers have applied for a patent for their method.

Full Day Time Lapse - Skunk Bay, WA

This video will help you SEE and understand the changes that occur when viewing distant objects during different times of the day. Many factors are at play here and they all have an effect on what we can see: angular resolution, atmospheric humidity, temperature changes of both the air and water, atmospheric compression, atmospheric mirroring, refraction/diffraction of light, and high/low tide levels, just to name a few.

These combine to produce magnification and/or positional changes of distant objects, looming effects (stretching the top of objects), compression of the lower parts of objects which "squashes" them, the obstruction/"hiding" of far-away objects due to atmospheric particulates and precipitation (haze, fog, rain), etc.

The point is, none of the changes you are seeing have anything to do with the curvature of the mythical globe you've been told that you live on.

These natural changes confuse most of us because we don't realize what's actually happening. It's important to research these effects and understand how they work in combination with one another AND how those people that hide the true shape of our world from us have used our limited powers of observation and knowledge to fool us into believing we live on a spinning ball.

Research flat earth. Someday, you'll be happy you did.

New camera offers ultrafast imaging at a fraction of the normal cost
Capturing blur-free images of fast movements like falling water droplets or molecular interactions requires expensive ultrafast cameras that acquire millions of images per second. In a new paper, researchers report a camera that could offer a much less expensive way to achieve ultrafast imaging for a wide range of applications such as real-time monitoring of drug delivery or high-speed lidar systems for autonomous driving.
