09:02 when Derek says "I brought a special lens" and Dr. Shaw replies "Uuuuhh special lens!!!" exactly as a kid would do, was priceless! He works in THAT lab surrounded by million of dollars of ultra specialized tools and he gets real excitement for a camera lens. What a man! Loved every microframe of this video :)

I like how he talked about using new measurement allowing for scientific discovery that leads to better measurement. When you work with machining or woodworking (relatively old and well known things that regular people can interact with), you know that step one of making something flat is to have something flat. We've bassically spent thousands of years developing and refining the tools that allow us to precicely construct the world around us, and that's fascinating.

YAHUsha 9 ヶ月 前
Jesus Christ is the propitiation for the whole world's sins. They that believeth and are baptized (with the Holy Spirit) shall be saved; but they that believeth not shall be damned. Those led by the Holy Spirit do not abide in wickedness. *God is ONE manifesting himself as THREE;* the Father, the Son, and the Holy Spirit! Bless him! *For these three are one.* As I am led by the Holy Spirit, nothing I state is a lie, but the truth of God. Anyone who tells you differently is misinformed or a liar. They do not know God, nor led by him. Anyone who *claims* to be a Christian and is against what I am doing, and where I am doing it; the Holy Spirit does not dwell within them, they lack understanding. They know not God, read his word, and their religion is in vain. Do not hear them, they will mislead you, the lost cannot guide the lost.
YAHUsha 9 ヶ月 前
Another truth many have been deceived of: When you trust in God and cast your cares (worries, anxiety, depression, suicidal thoughts) upon him, they will be NO MORE! Know that there is power in the name Jesus Christ! His name casts out demons and heals! The world is wicked, evil, and of the devil. I too, was a wicked sinner of the world before I opened my heart to God. I am living proof of God's work and fruitfulness! He is an active God who hears the prayers of his! God's children are set apart (holy) and righteous. The devil is a liar that comes to steal, to kill, and to destroy; that includes your relationship with God. Open your heart to God, repent of your sins (he will forgive you), and let him direct your path. Draw nigh to God, and he will draw nigh to you. Cleanse your hands and purify your heart, lest you walk with the devil and follow him to hell.

Those uses were really really important. You can't always use kibble balance to set a standard for all of these industries. Test weights really come into play to the practicality and usefulness of metrology. Measurements are just literally numbers if there's no actual thing that represents it. We don't have to always excite Caesium atoms just to make sure the accuracy of 1 second. A well engineered standard will always support a truly working physics at hand.
James Dinius
James Dinius 7 日 前
Exactly. Things like kibble balances and atomic clocks are very precise, but are not practical for most industrial, and sometimes even scientific applications. Standards translate this precision into a form that these applications can make use of.

I'd love to know more about the isolation techniques used to prevent interference when measuring at the femtogram scale.It's hard to imagine that a person just being in the same room of that device wouldn't cause interference of some kind.
