What do you do to keep all the pieces you play memorized and in good shape?
I use an iphone app, Encores! to maintain my amateur repertoire of about 55 (and counting) pieces I am able to play. It helps me came back to them in a casual effortless way. #guitar #music

Reason to Hope, by @dgardner. We're oblivious to progress because it happens too gradually to make the news, and because we are biased to notice sudden, vivid, and negative events. https://t.co/4tARPMeZ6E

It certainly happens to me, unless I play mostly the same pieces every time.

[Gabriel Chacón @gchacon66]

Many musicians tell me this happens to them more often than they’d like.

New ideas on how to produce safer and cleaner nuclear energy about to become a reality…

[Bill Gates @BillGates]

I’ve been waiting for this day for nearly 20 years: Today, we broke ground on the first-ever Natrium plant in Kemmerer, Wyoming. This next-generation nuclear power plant is a big step towards safe, abundant, zero-carbon energy. https://t.co/OxMYdU5o4R

“Pronto se planteó un problema: hacen falta demasiados dibujos para dar cuenta del mundo exterior e interior —⁠desde las pulgas a las nubes, desde el dolor de muelas al miedo a morir⁠—. El número de signos no dejaba de aumentar, sobrecargando la memoria…

Nuestra «D» representaba en origen una puerta, la «M» el movimiento del agua, la «N» era una serpiente y la «O» un ojo. Todavía hoy, nuestros textos son paisajes donde pintamos —⁠sin saberlo⁠— el oleaje del mar, donde acechan peligrosos animales y miradas que no pestañean”

#OTD in 1996, Carl Sagan died: 27 years without Carl

«When my husband died, because he was so famous and known for not being a believer, many people would come up to me ― it still sometimes happens ― and ask me if Carl changed at the end and converted to a belief in an afterlife.

They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl.

But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting.

Every single moment that we were alive and we were together was miraculous-not miraculous in the sense of inexplicable or supernatural. We knew we were beneficiaries of chance.

That pure chance could be so generous and so kind. That we could find each other, as Carl wrote so beautifully in Cosmos, you know, in the vastness of space and the immensity of time. That we could be together for twenty years. That is something which sustains me and it’s much more meaningful.

The way he treated me and the way I treated him, the way we took care of each other and our family, while he lived. That is so much more important than the idea I will see him someday. I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful».
