I would just like to say for the record that I intensely dislike Safari on iPads where it will break out a new page that floats above into the side of your current page without any controls to close it or ability to flick it off the screen easily or intuitively.

72 / 22% = dollar supply doubled in 3.27 years...

22% of all US dollars were made in 2020. Let that sink in.

Compare your banks security encryption to bitcoin's Here are the steps-- Create a signature: Hash the transaction to sign Select a random number Calculate the ECDSA curve point (x1, y1) by multiplying the random number by the elliptic curve base point (G) Calculate r and s using the private key, the ECDSA curve point, and ECDSA signing algorithm. The signature is the pair (r, s). Verify a signature: Hash the transaction that was signed Calculate u1 and u2 using the public key, the signature values r and s, and ECDSA verification algorithm Calculate the curve point (x1, y1) using u1, u2, and the public key If r is equivalent to x1 the signature is valid

“In states such as California and New York, theater owners large and small have expressed bewilderment as authorities have allowed some indoor establishments such as restaurants, bowling alleys and churches to open with capacity restrictions while requiring theaters keep their doors closed.“ WSJ

"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery. The findings, published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene—a single layer of carbon atoms—ripples and buckles in a way that holds promise for energy harvesting. The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado's team found that at room temperature the thermal motion of graphene does in fact induce an alternating current (AC) in a circuit, an achievement thought to be impossible. In the 1950s, physicist Léon Brillouin published a landmark paper refuting the idea that adding a single diode, a one-way electrical gate, to a circuit is the solution to harvesting energy from Brownian motion. Knowing this, Thibado's group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide separate paths through the circuit, producing a pulsing DC current that performs work on a load resistor. https://phys.org/news/2020-10-physicists-circuit-limitless-power-graphene.amp

https://www.freep.com/story/news/local/michigan/detroit/2020/10/02/ddot-detroit-bus-shutdown-drivers-service-work-stoppage/5892655002/ The bus drivers are paid $12 per hour to be spat on by anti maskers and when they get sick they don’t even have health insurance? Its gonna get worse. Imagine trying to social distance during snow. Wanna pack in or wait 45 mins for the next bus? Here's the latest case/death charts for Michigan, with running 7-day averages: https://www.statmap.org/?LOCALE=Michigan#data 7-day average cases trending up, deaths remain flattened. Currently Michigan is at 70.98 deaths per 100k population. That ranks them 10th among states in per capita deaths:
