Would there be a smartphone today without Einstein's discoveries?

I told a friend that without Einstein's discoveries he would not have his smartphone. I thought about the components (display, CPU, radio waves, ...) containing discoveries made by Einstein. But I can't name an exact example. My friend told me it's all pure electronics. No relativity and so on...

Wrench Sizes

When it comes to managing the wrench sizes, it is relatively easier than the sockets. It’s because sockets involve different ratchet drive sizes, but the wrenches don’t. However, you still need to have some basic information to arrange them or correctly use them.If you want to know about different s

XBee Communication For Flying Device

I am currently working on a project that will be a flying device, so i require a bit of range for control. I have been looking around for control systems, and have come across the XBee-PRO 802.15.4 RF Modem, which seems to me to be the best solution for me. Has anyone used this device before? If so

X- and Ku-Band Small Form Factor Radio Design

Many aerospace and defense electronics systems in the satcom, radar, and EW/SIGINT fields have long required access to a portion, or all, of the X and Ku frequency bands. As these applications move to more portable platforms such as unmanned aerial vehicles (UAVs) and handheld radios, it is critical

Y-Δ transform proof using superposition

In the wikipedia page and on every book they proof the transformation by equaling the the equivalent resistance between any pair of terminals while disconnecting the other node.https://en.wikipedia.org/wiki/Y-Δ_transform Why this should make the two circuits equal? How can we apply superposition he
