electromagnetic spectrum

a pointless thing to learn. you will forget all those times you spent in your physics lessons at school therefore you do not need to learn something as stupid and pointless as this.

girl 1: hey, i just figured out what the electromagnetic spectrum is!
girl 2: why did you do that? it's a waste of time.

Charter Spectrum

One of the most awful ISPs out there. The 99% up time is wonderful, yet the "1%" down time is as bad as 911.

They love to throttle your speeds on account of their small wee wees.

Bro, my internet is making me glitch all over the place. I'm just trying to get the dub bro. F CHARTER SPECTRUM

spread spectrum

A signal structuring technique that employs direct sequence, frequency hopping or a hybrid of these, which can be used for multiple access and/or multiple functions. This technique decreases the potential interference to other receivers while achieving privacy and increasing the immunity of spread spectrum receivers to noise and interference. Spread spectrum generally makes use of a sequential noise‑like signal structure to spread the normally narrowband information signal over a relatively wide band of frequencies. The receiver correlates the signals to retrieve the original information signal (NTIA)

Normal scanners cannot get spread spectrum transmissions.

autism spectrum disorder

A neurodevelopmental condition characterized by impaired social skills and restricted interests or repetitive behavior. Symptoms usually begin in early childhood.

Although most people with autism spectrum disorder (people "on the spectrum") are functionally impaired, some thrive occupationally or academically, especially people with Asperger's syndrome, who have no delays in language development and/or IQ.

A common misconception is that people on the spectrum lack empathy, the affective part of empathy seems to be unimpaired compared to people without the condition. This means that people on the spectrum often have the capacity for compassion and morality.

Complications include bullying, unemployment (prevalence of about 90%), suicide and self-harm.

Treatment is limited and the efficacy of specific interventions has been disputed.

The heritability of the condition is about 90%. Specific environmental risk factors known to contribute to the condition include autoimmunity. Disproven environmental factors include vaccines.

Although the condition causes significant suffering for many, some have disputed the characterization as a disorder altogether, especially because the restricted interests commonly seen in the condition can include occupationally or socially useful subjects like math or physics. People on the spectrum often hyperfocus on their area of interest.

Several historical figures like Einstein are claimed to have been on the spectrum, these claims are unproven.
