He Jackobshavn Isbrae glacier It reached a speed of 45 meters per day, as recorded in August 2004. Thus, it is the glacier that has moved at the fastest speed, as far as we know.
The speed was attributed to an influx of warm seawater into Disko Bay, on the west coast of Goenland.
Titanic and the iceberg the size of Belgium
Since then, the glacier has slowed considerably, especially after a very cold period in 2013.
The curious thing is that it is very likely that the Titanic sank when it collided with an iceberg that broke off from this glacier that holds the speed record. It's not strange something like that: The Jakobshavn Glacier drains 6.5% of the Greenland ice sheet and produces about 10% of all Greenland icebergs. Approximately 35 billion tons of icebergs break off from the fjord each year.
Still, it was not the largest iceberg ever documented that stood in the path of the largest ship. That title is held by another: on November 12, 1956, the crew of the USS Glacier sighted a tabular iceberg with an estimated area of more than 31,000 square kilometers, that is, more than the surface of Belgium.
The iceberg measured 335 kilometers long and 97 kilometers wide. They spotted it west of Scott Island, in the Antarctic Ocean.

Aptera has opened the possibility of placing orders for a solar electric vehicle that can be equipped with batteries that allow a range of up to 1,600 kilometers. He Aptera solar EV provides up to 72 kilometers of autonomy per day without needing to be plugged in.
Its manufacturers claim that its 180 small solar panels, which make up an area of more than three square meters, will collect enough energy to make all this possible.
Aptera
With a vaguely aeronautical-looking two-seat cabin, the Aptera has an 'unheard of' drag coefficient of just 0.13. Compare that to, say, the Concept V's 'incredibly low' 0.24 drag coefficientolkswagen ID Space Vizzion. It is also completely constructed of carbon/kevlar/flax composites, which makes it very light and resistant.
As for the engine, there are multiple options available, with liquid-cooled electric motors on either the two front wheels or all three.
Battery sizes will also vary, so a range of 400, 644, 965 km or up to 1600 km. To get an idea of how efficient this three-wheeled vehicle is, the Tesla Model S P100D had a radical increase in efficiency this year and can now reach 650 km with a battery of the same size.
To be fair, Tesla has actually already put its cars on the road, and Aptera has only reached the production prototype stage so far. But it is ready to accept reservations for the 'Paradigm' and 'Paradigm+' special edition vehicles that will be produced in 2021.

Dunbar, the pilot of Catch 22, of Joseph Heller, that if time flies when you're having fun, the best way to slow down the passage of time is by making life as boring as possible.
That is not what you are going to get with this scholarly, exquisite book of Santiago Alvarez:De women, men and molecules. A book punctuated by unpublished veins in the history of science, and the best: how these veins connect with others, allowing us to see new forms emerge: laboratories, mirrors, etc.
An alphanumeric book
The world does not systematize its scenery with the same architectural capacity that a writer does. But Ălvarez achieves it without resorting to fiction: he simply analyzes scientific reality from such wonderful aspects and angles. that highlight charms from the world of fantasy.
In other words: if you applied a stethoscope to me to listen to my heart rate while I was reading this work, you would notice my heart was racing with emotion.
That's why I have kept my eyes wide open all the time. And I have learned the unspeakable; In addition to the fact that Ălvarez does his bit so that we forget to divide people into âliteraryâ or âscienceâ people, betting on an alphanumerism that only the epistemically hungry farm at the expense of academic divisions.
Without a doubt, essential, like another book in this collection that is already becoming one of my favorites: Science in literature, of Xavier Duran.
How do artists, writers and musicians view chemistry? And chemists, what vision do they have of topics as far apart as visual communication, magnetism, the image of a mirror or the relationship between music and alchemy? Of Women, Men and Molecules is located at the intersection of the sciences and the humanities, and brings together those two complementary views on us and the reality that surrounds us from a place little traveled, but no less necessary and creative. This is a popular book about chemistry, and at times it is also a history of philosophy, painting and music, and sometimes even an anecdote with which Santiago Ălvarez allows us to look at the world with the eyes of a restless and observer. In short, from the different ways in which chemistry is present in literature and art.
