TLAs: Are Common These Days

TLAs: Are Common These Days 150 150 IEEE Pulse
Three-Letter Acronyms (TLAs) are very popular, and can be found in almost everything written or spoken these days. Why? Perhaps it is because we are busy, lazy, or maybe there is just a fascination with things that come in threes. Most likely, we write or speak in TLAs because it makes our language more efficient at conveying information with the least possible cost. TLAs transform largely redundant information into a more expeditious form. read more

It was my routine to stay home on Wednesdays and write papers, author books, make teaching plans, or grade papers and reports. I would be in my office Monday, Tuesday, Thursday, and Friday, but everyone in our department soon got used to my absence on Wednesday. read more

Alone With My Thoughts 150 150 IEEE Pulse
They call them earworms, those songs and ditties that roll around in your head whenever there is nothing else going on. Even when you want to be alone, they are always there, whether one wants them or not. And they resist being forgotten. Some are simple little things, jingles that keep ringing in my ears all day and all night long. They can be triggered by some simple reminder, like catching a television or radio ad, hearing children singing familiar songs, or listening to a choir sing a catchy gospel melody. “It’s A Small World” is particularly deadly. read more

Getting Past the Know-It-All Stage

Getting Past the Know-It-All Stage 150 150 IEEE Pulse
A little knowledge can be a dangerous thing. Most of us have heard of this admonition, and it applies directly to engineering education. It turns out that people who know just a little about a subject greatly overestimate their understanding and abilities. “The Dunning–Kruger effect is a cognitive bias in which people wrongly overestimate their knowledge or ability in a specific area. This tends to occur because a lack of self-awareness prevents them from accurately assessing their own skills”. read more

Are Viruses Just Spores?

Are Viruses Just Spores? 150 150 IEEE Pulse
Something amazing happened early in the history of the Earth. Molecules were formed that had the unusual capacity to reproduce. And, not only that, but these molecules reproduced to the limit of the resources available and competed with other, similar, molecules to utilize every available reserve necessary to their growth and reproduction. These molecules were nucleic acids. read more
