GPS Hidden Messages - Computerphile22 Cards

GPS signals are extraordinarily weak, comparable at transmission to a dim light bulb and nearly negligible at Earth.

@ruthkellan added

Military GPS authentication uses encrypted signals and restricted keys, making spoofing much harder because attackers cannot predict signal contents.

Shor's Algorithm for Quantum Computing - Computerphile16 Cards

Nobody knows when quantum computers will break cryptography. Estimates range from roughly five years to hundreds.

@ruthkellan added

Quantum superposition does not require parallel realities or alternate universes to explain it.

Quantum Machine Learning - Computerphile12 Cards

Quantum data becomes classical through probabilistic measurement, so returning an answer usually takes repeated executions called shots.

@ruthkellan added

Reconstructing an entire quantum state requires huge numbers of shots, so applications estimate a relevant property instead.

Why AI is like a (Clever Hans) Horse - Computerphile12 Cards

A music classifier identified an extremely sparse, unnatural frequency collection as blues, though it sounded nothing like blues to people.

@ruthkellan added

Blend 100 individually sufficient blues signals and the model still classifies the result as blues, despite muffled ambient noise.

The Problem with Time & Timezones - Computerphile10 Cards

Samoa skipped December 30, 2011 when it moved across the International Date Line.

@ruthkellan added

In Libya, the government changed time-zone rules in 2013 with only a couple of days’ notice.

Floating Point Numbers - Computerphile9 Cards

In programming, 0.1 + 0.2 differs slightly from 0.3 because neither has an exact finite binary representation.

@ruthkellan added

Adding three rounded representations of one-third can produce 0.99999999... instead of exactly 1.
