I grew up with The Powers Of Ten - amazing and still fascinating today. The really surprising thing is that at any scale everything seems similar, such as planets revolving around a star, whole galaxies spinning inside a super galaxy cluster and even electrons spinning around the nucleus. Then consider time also has its own Powers of 10 from star lifetimes of billions of years to chemical and nuclear reactions happening in fractions of nanoseconds.
Consider that even the densest materials are almost 100% vacuum and that a continuous stream of ~50000 Billion particles second fly straight through our bodies at very close to 100% of the speed of light without ever hitting us or anything else as they pass right through Earth... They are only 8 minutes old while the light from the Sun reaching us is 170000 years old. Mindboggling!
You're quite right we're insignificant, the dust left over of a supernova. It's interesting all the searches for extra terrestrial life are focussed on something very similar to life on Earth. But who says life can't occur in dramatically different scales of time, dimension, temperature, pressure, or building blocks?
All this makes those who celebrate a dead guy coming back to life look even more ridiculous!
What is even more amazing is that it always seems to come back to this 'ressurected dead guy'. That in itself says much! If he is who he said he is, then he is more marvelous than all we can conjure from 10E-15 to 10E30!
Comparing to the shorlived electronics and device age that we lived in, Hubble is marvel of engineering and technology. Many like myself have grown up amazed by the space pictures that Hubble gave to the world. I can only wish Hubble many more years of service.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
