Download Scale Drawings of Everything at Dimensions.Guide via Lifehacker

September 21st, 2019 Comments off
Just one of those quirky sites — and excellent resources — that I happen across in my daily reading. Just the thing if you need to compare the size of a T-Rex to a human being  and tons of other dimensions. — Douglas
The design site Dimensions.Guide is a clip art library for designers, architects, and anyone else who needs precise scale drawings. Every scale drawing in its database is composed in the same clean line-art style. Drawings include sports equipment, cars, furniture, people (in various poses and sizes), computers and phones, plants and animals, room and landscape layouts, and even Marvel characters. And it’s all free to use in your own projects.

‘All Must Have Prizes’: Citizen Science and the Environment – Professor Carolyn Roberts via Gresham College

'All Must Have Prizes': Citizen Science and the Environment - Professor Carolyn Roberts via Greshem College

Prior to the twentieth century, most environmental observations such as rainfall amounts and air temperatures were made by lay observers with interest and time on their hands. Later on, such measurements moved largely into the realms of professionals, but today the role of amateur observers is being revisited. The advent of smart phones and GPS is increasingly allowing citizen observers of wildlife, ecology, air and water quality, and flooding, to enhance our understanding of environmental science. What opportunities exist for individuals to help to solve some of the most complex problems on Earth? And what motivates people to join an environmental research team?

The transcript and downloadable versions of the lecture are available from the Gresham College website.

Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 2,000 lectures free to access or download from the website.

How Do Sinkholes Form? via YouTube

September 2nd, 2019 Comments off

Sinkholes form through both natural and human-made processes.

Most of us think about erosion on the surface of the earth, but erosion can occur in the subsurface as well. In fact, scientist and engineers have a very creative name for just such a process: internal erosion. If just the right factors come together in the subsurface, some very interesting things can occur, including sinkholes.

This Beautiful Short Film Recreates the Moon Landing Using Thousands of NASA Photos via Gizmodo

July 5th, 2019 Comments off
It is always amazing to revisit history you lived through. I remember the Apollo program well. I even had a papercraft model of the LM (Lunar Module) that I got from a local gas station as a giveaway once. The adventures of the Apollo astronauts was the underlying theme of my entire childhood. — Douglas

Jellyfish at the California Science Center – A Minute in Los Angeles 16 [Video]

January 22nd, 2019 Comments off

Lovely floating jellyfish cruise about their tank at the California Science Center in Exposition Park

Find yourself immersed in the majestic grandeur of a giant kelp forest, where algae called kelp grow as large as trees and support a tremendous variety of life. You may be amazed to discover that examples of this spectacular ecosystem, which in the wild can support over 800 species, exist right off the coast of Southern California. Peer into our 188,000-gallon tank and get a glimpse of what life is like in these special underwater forests. The aquarium takes precautions by having great vitamins from https://www.ukmeds.co.uk/ to treat jellyfish stings in case their staff gets stung. And find the species you see in the tanks on our new iPads to learn more about them!

Reading – Astrophysics for People in a Hurry by Neil deGrasse Tyson – 19 in a series

June 5th, 2018 Comments off

I’ll be highlighting books that I am reading (or re-reading) on all sorts of topics this year — Douglas

Reading – Astrophysics for People in a Hurry by Neil deGrasse Tyson – 19 in a series

Reading -  Astrophysics for People in a Hurry by Neil deGrasse Tyson - 19 in a series

It takes a special talent to explain science — and write a book on highly scientific topics — without erring in 2 possible ways. Typically science books for the layman go into far too much detail with far too much technical jargon and quickly leave the reader disheartened. They want to understand, but without a good intermediary to help bridge the gap from expert to everyman, they fail.

Secondly, science can be explained in such a simplistic way that the reader is left wondering about its importance to the world and also, perhaps, about why scientists find it so difficult to make theoretical and experiential headway into the particular topic. Scientists are always trying to find the “sweet spot” between over complication and oversimplification and it is a difficult path to walk.

Thankfully, Neil Degrasse Dyson has, for whatever reasons, been blessed with the ability to clearly explain complicated scientific concepts to the average person without either talking over their heads or, even worse, talking down to them. This collection of essays holds together nicely as a book, something that doesn’t always happen. Thinking back over my reading there were perhaps 2 times when I lost the thread of what was being discussed, but a quick re-read of a particularly troublesome section seemed to clear it up, at least enough for my purposes. When I read A Brief History of Time by Stephen Hawking† there were many times when I felt hopelessly lost in the world of theoretical physics, but Astrophysics for People in a Hurry kept me involved, enlightened and educated throughout.

While many of us will never have a need for a deep knowledge of Astrophysics, I am a great believer in knowing a little about a lot. Learning new theories, reading new books and absorbing new ideas keeps us growing throughout our lives. Pick up a copy of Astrophysics for People in a Hurry and I think you will enjoy the trip through the cosmos in all its, sometimes confusing, glory.

From Amazon.com…

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There’s no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson.

But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.

While you wait for your morning coffee to brew, for the bus, the train, or a plane to arrive, Astrophysics for People in a Hurry will reveal just what you need to be fluent and ready for the next cosmic headlines: from the Big Bang to black holes, from quarks to quantum mechanics, and from the search for planets to the search for life in the universe.
