“Before he died in 2013, the great sociologist Robert Bellah said that his view of everything he’d studied across his life was tilted on its axis by this late recognition: when mammals began to bring forth offspring from the center of their bodies, spiritual life became possible. With apes and far more with humans, the period of necessary parental care—care in order for the offspring to survive—became longer and longer. The long helplessness of the child generated a sphere of softening, experimentation, and creativity in self-understanding and shared life.”

In quantum computing, the cat state, named after Schrödinger's cat, is the special quantum state where the qubits are in an equal superposition of all being |0> and all being |1>, i.e. (in Bra-ket notation): |00...0> +|11...1>.
In other quantum mechanics contexts, according to The New York Times for example, physicists view the cat state as composed of two diametrically opposed conditions at the same time, such as the possibilities that a cat be alive and dead at the same time. This is sometimes called the many worlds hypothesis. More prosaically, a cat state might be the possibilities that six atoms be spin up and spin down, as published by a team at NIST, December 1, 2005. This spin up/down formulation was proposed by David Bohm, who conceived of spin as an observable in a version of thought experiments formulated in the 1935 EPR paradox. David Bohm and Yakir Aharonov later attained recognition for the Aharonov-Bohm effect, 1959.
Erwin Schrödinger formulated this concept by positing a condition in which one intrinsically does not know something, and that only by performing an observation could one know it. He dramatized the situation by positing a moral choice (bestowing life or death on a cat). Later formulations have de-emphasized the life/death choice by showing the possibility of a cat state which is independent of human action.
Schrödinger's cat is a thought experiment, usually described as a paradox, that Austrian physicist Erwin Schrödinger devised in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects.
A ability to select more then one block at a time by holding CMD/CTRL.
The idea would be to also making moving blocks to a collection a lot easier by allowing the movement of more than one block at a time. I would like to be able to move up to 10 blocks at a time to another collection.
someday, a network diagram of all of are.na ~ a setting where each block is a node and you can visually see where it is connected, or be able to see how different channels are related. you could zoom out or zoom into this diagram for a more intimate or broad view
