Los mecanismos flexibles tienen muchas ventajas sobre los dispositivos tradicionales.
Visité el Compliant Mechanisms Research group en la Universidad Brigham Young y hablé con el profesor Larry Howell:
https://www.compliantmechanisms.byu.edu

En el enlace anterior, pueden descargar archivos de impresión en 3D para hacer algunos de los objetos en el video, además de aprender más sobre los mecanismos flexibles.

Lo que aprendí sobre los mecanismos conformes lo resumo en las 8 P de los mecanismos flexibles:

1. Recuento de Piezas (reducido por tener partes flexibles en lugar de resortes, bisagras)
2. Procesos de producción (muchos, nuevos, diferentes habilitados por diseños flexibles)
3. Precio (reducido por tener menos partes y diferentes procesos de producción)
4. Movimiento Preciso (sin holguras, menos desgaste, fricción)
5. Performance (no requiere lubricante)
6. Proporciones (reducidas a través de diferentes procesos de producción).
7. Portabilidad (ligero debido a diseños con piezas más simples y reducidas)
8. Previsibilidad (los dispositivos son confiables durante un largo período de tiempo)

Key aspects of pyramid construction from quarry to completion.
Check out Audible: http://bit.ly/AudibleVe
Live show in Alabama: http://bit.ly/VeRAOI

The most common misconception about the pyramids is that they were built by slaves. Recent archeological evidence suggests they were instead constructed by paid workers. Some may have performed this work as a form of tax payment for several months of the year. Skilled engineers would have planned and orchestrated the building. An estimated 10,000-20,000 people would have been working on a pyramid at any one point in time. They were well fed and provided with shelter near the pyramids. Plus their burial sites close by indicate they were respected and were not slaves.

Much of the limestone was quarried from the Giza plateau itself, meaning the stones did not need to be transported far. The granite casing of Menkaure's pyramid, on the other hand, was transported from Aswan, around 600 miles, or 1000 km up the Nile.

The Earth is clearly old, but exactly how old was difficult to work out. People long believed the Earth had only existed for several thousand years. Then, in the 1800's, a study of geological features (including fjords) led scientists to the conclusion that the planet must be much older - at least millions of years old. Later, the discovery of radioactivity provided a mechanism by which the Earth's core could be continually heated. This meant it was much older than previous estimates of 20-40 million years based on the cooling rate of the Earth. Today through many different methods we have established that the Earth is roughly 4.54 billion years old!

I always wanted to know why film looked better than video. Moving electronic images have as long a history but were invented for a different purpose. This video was sponsored by B&H Photo: https://www.bhphotovideo.com

This is a video I've long wanted to make, about what makes video look like video and, up until 10 years ago or so, not as appealing as film. I grew up with the two technologies (film and video) in parallel and to me they always seemed like two ways of achieving the same ends: recording and replaying moving images. But their histories are quite distinct. Film was always a way to capture moving images for later replaying. Video started out as a way to transfer images from one place to another instantaneously. This dates back to the first fax machine, mechanical TV, live broadcast tv and ultimately videotapes. This history focuses on the early decades of video and not the more recent switches to chip cameras and solid state storage. Maybe that's a story for another day.

What is radiation? Are all types harmful? What are the most common sources of damaging radiation? Most people view radiation as harmful and negative without understanding what makes it potentially damaging and which forms should be avoided. For example, many felt radiation from mobile phones probably caused cancer but few focused on the carcinogenic effects of UV rays.

Letra de Sólo Tu Gracia, de Daniel Calveti


(Señor, estamos agradecidos por tu gracia,
porque tu gracia nos ha arropado,
nos tiene aquí 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. Haz click para suscribirte: http://bit.ly/DanielCalvetiOficial
