I'm not sure how alarmed to be about artificial intelligence. Personally I think it's really hard to predict when we'll create a machine that essentially has consciousness. That's because we don't know what consciousness is, how it works, what's required to create it etc. So It might be technologically around the corner or a hundred years away.

What I do think is more predictable is the development of autonomous weapons that use AI to be the most effective killing machines of all time. That is scary. As outline by people like Musk and Hawking, this threat is clear and present so we should address it. I would like to see us agree as a species not to develop these sorts of weapons because if any one state does develop them, they would be very hard to stop.

The Earth spins on its axis, completing a full revolution every day. By why does it do this? One of the most common misconceptions in physics is the belief that constant motion requires a constant force. So many people believe there must be some force in the Earth (e.g. gravity, centrifugal force) that keeps it spinning. In truth, no force is required because a fundamental property of mass is that it maintains its state of motion in the absence of external forces. This property is called inertia.

Research has found some human brains can pick up on rotations of geomagnetic-strength fields as evidenced by drops in alpha wave power following stimulus. For more, see https://ve42.co/magneto

Mars InSight will be the first to detect seismic activity on Mars’ surface, first to measure rate of heat transmitted from interior, first to dig nearly 5m down, first to measure magnetic fields on Mars’ surface, and first to use a robotic arm to place instruments on the surface of Mars (assuming it lands of course…)

A basketball and a 5kg medicine ball are dropped simultaneously. Which one hits the ground first? It seems obvious that the heavy one should accelerate at a greater rate and therefore land first because the force pulling it down is greater. But this is forgetting inertia - the tendency of mass to resist changes in motion. Therefore, although the force on the medicine ball is greater, it takes this larger force to accelerate the ball at the same rate as the basketball.

Newton's Law of Universal Gravitation can be summarized as "all mass attracts all other mass." But if this is true, why don't we notice the gravitational force of attraction between everyday objects? The reason is because the gravitational force is quite weak.

How does a sailboat work? The standard idea is that the wind pushes the sails from behind, causing the boat to move forward. Although this technique is used at times, it is not the most efficient way to sail a boat (and it means the boat can never go faster than the wind). Lift is the key mechanism driving a boat forwards. As air flows over the sails, it moves faster over the outer side, creating lower pressure than on the inner side. This produces a force which is mostly to the side and a bit forwards. Lift on the centerboard pushes to the opposite side, cancelling the sideways force and adding a forward component of force to the boat.

The Veritasium treatment of the final transit of Venus this century. The weather behaved for some key moments allowing me to observe Venus passing across the disk of the sun. The transit of Venus is steeped in historical significance. Observations of the transit in 1769 led to the first really accurate calculation of the Earth-Sun distance (or one astronomical unit AU). Since Cook was in Tahiti he then mapped the East coast of Australia and parts of New Zealand.

March 26 segment on live TV talking about solar storms and my upcoming trip to the Great White North. As you watch this I will probably be on a plane high over the pacific.
PS a student recently told me that my hair to beard ratio is a bit off and watching this clip I tend to agree. However, it is still -20 C at night in Alaska so I'll need all the insulation I can get.

NASA TV airs a variety of regularly scheduled, pre-recorded educational and public relations programming 24 hours a day on its various channels. The network also provides an array of live programming, such as coverage of missions, events (spacewalks, media interviews, educational broadcasts), press conferences and rocket launches.

In the United States, NASA Television's Public and Media channels are MPEG-2 digital C-band signals carried by QPSK/DVB-S modulation on satellite AMC-3, transponder 15C, at 87 degrees west longitude. Downlink frequency is 4000 MHz, horizontal polarization, with a data rate of 38.86 Mhz, symbol rate of 28.1115 Ms/s, and ¾ FEC. A Digital Video Broadcast (DVB) compliant Integrated Receiver Decoder (IRD) is needed for reception.

In the next eight minutes, you’ll experience a twenty-five-and-a-half-day mission from roll-out to recovery of the first integrated flight test of NASA’s Orion spacecraft and the Space Launch System rocket, launching from the agency’s Kennedy Space Center in Florida. This uncrewed mission will be the first in a planned series of exploration missions beyond the moon, signaling what astronauts who dare to operate in deep space will experience on future flights.

What's different about sleeping in space? Former NASA astronaut Mike Massimino breaks down all the differences between sleeping on Earth and sleeping in space. Is there a difference between sleeping upside down and sleeping right-side up? Do you get your own bedroom? What kind of alarm clock does an astronaut use?

Mike Massimino is a former NASA astronaut, senior advisor for space programs at the Intrepid Museum, and professor at Columbia University.

Letra de Sólo Tu Gracia, de Daniel Calveti
(Señor, estamos agradecidos por tu gracia,
porque tu gracia nos ha arropado,
nos tiene aqui hoy, te amamos Señor.

Solo tu amor nos ha sostenido,
y hoy podemos cantar de tu tierna gracia,
te amamos a ti Señor.)

Solo tu gracia es la que abre puertas
Solo tu amor es quien me sostiene
Y yo no entiendo
Porque me escogiste habiendo muchos aquí
No se lo que pasa pero gracias te doy
Porque en tu mirada me viste tu a mi
Y habiendo otros que hagan lo mismo
Me escogiste a mí

Solo tú abres puertas que yo no entiendo, no.
Y si otros me preguntan porque estoy aquí
Yo les contestaré:

No es por mis fuerzas,
No es por lo que sé hacer
No es por lo que tengo
Es por tu tierna gracia
Tu tierna gracia
Tu tierna gracia
Y nada más

(Si Dios te ha dado algo, no es por tus fuerzas
solo es su gracia
no importa en que posición estés
no importa todos los bienes que puedas tener
es su gracia que te ha llevado allí.
Solo hay que tener un corazón agradecido
y decir: Señor, es tu gracia,
es tu gracia que nos sostiene.)

No, no es por mis fuerzas,
No es por lo que sé hacer
No es por lo que tengo
Es por tu tierna gracia
Tu tierna gracia
Tu tierna gracia
Y nada más.
