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!

Hubble is marvel of engineering and technology, indeed. So it is even more surprising that it needed "glasses" to reach its full potential. Which then turned out to be enormous.

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!

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.

Hubble makes us humble!

By just looking at this pciture of a Nebula which is 6400 light years away from us, makes us humble. 

We the creatures on this mother earth are so small compared to this cosmos that inn the cosmos picture we are not even a spec of dust.

But we also discover partciles which are Nano .

It is just intriguing to think , at what level of micro or mega we are in the scale of the cosmos.

Scientific advancement and new discovery, of course, but I think one of the great successes of Hubble is the way in which it has brought fabulous images like these to the general public.

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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
