Angular Momentum

Paul Andersen explains rotating object have angular momentum. The angular momentum of a point object is the product of the distant from the center of rotation and the linear momentum. The angular momentum of an extended object is a product of the rotational inertia and the angular velocity. The change in angular momentum is equal to the product of the net torque and the change in time.

Religion and Literary Scholar Reza Aslan basically calls out comments by CNN hosts, and Bill Maher, as stupid and racist, in his beautifully learned fashion, for over-generalized arguments about “Islamic Countries”. Honestly, he makes them look like backwards ass dimwits.

Facile arguments… unsophisticated arguments...” ;)

Sculpting and painting in Virtual Reality - Oculus Rift DK2 + Razer Hydra & Tiltbrush

Info for video above:

3D Sculpting system for virtual reality using Razer Hydra as input controllers and displayed on the Oculus Rift Development Kit 2 VR headset.


Tilt Brush is a Virtual Reality Tool that paints the Space all around you. Paint thick, three-dimensional brush strokes, smoke, stars. Even light.

Nominated for four Proto Awards including Best Interaction Design, Most Innovative, and Best Overall Virtual Reality Application. Winner of Best GUI.

Both videos are pretty amazing. Can’t wait for VR to take off.
