Vision is the greatest gift to human. Like other creatures, even human eyes can see the beautiful things and others on the earth but perhaps only human can enjoy the beauty of the nature. We can’t see some things but some of them can be experienced. Some things are scientifically proven to exist but they are invisible to our eyes.

A new method to measure the arrival times of electrons could aid in the design of future electron microscopes.
For researchers working to develop the next generation of electron microscopes, understanding the details of electron beams is essential. Now a research team has observed the weak repulsion of electrons in a continuous beam with the highest precision to date by measuring the number of electrons arriving at a detector within a timeframe of less than 1 picosecond (ps) [1]. With improvements, the new technique may be able to pick up the repulsion attributable to the Pauli exclusion principle. The researchers think the work may eventually help engineers design more sensitive electron microscopes based on quantum principles.
Many natural events such as rain falling are uncorrelated: the fall of each raindrop is independent of every other raindrop. Given a certain time window, say 1 second, the likelihood that zero, one, two, or more raindrops will fall within a certain area is predicted by a statistical distribution called a Poissonian. If, however, the raindrops could interact, then their arrivals might be correlated or anticorrelated—the drops could fall together more often or less often, depending on whether the interaction is attractive or repulsive. Then the probability of similarly timed raindrops would be either super-Poissonian (occurring more often) or sub-Poissonian (occurring less often).
The highest sea cliffs in England have been hiding the oldest fossilized forest yet found on planet Earth. The long-lost ecosystem’s palm-like trees, called Calamophytons, are 390 million years old.
That’s roughly three or four million years older than the previous record holder, found across the Atlantic in New York State.
In southwest England, the red sandstone rock face where scientists found the imprints of logs, roots, and twigs was once considered “barren of trace fossils”

Towards Generalist Vision Transformer through Universal Language Interface.
This paper proposes a simple, yet effective framework, called GiT, simultaneously applicable for various vision tasks only with a vanilla ViT.
