Protecting American migratory birds

Dear Kitty. Some blog

This March 2017 video from the USA says about itself:

Bird Migration in North America

An overview on how and why birds migrate, including species such as the Yellow Warbler and the Woodthrush, as well as challenges migratory birds face today. This educational video was completed for ‘Birds Ecosystems and People’ at Allegheny College.

From Cornell University in the USA:

Scientists use eBird data to propose optimal bird conservation plan

The goal is to conserve habitat and protect migratory birds

April 15, 2019

A new paper published today in the journal Nature Communications shows a blueprint for conserving enough habitat to protect the populations of almost one-third of the warblers, orioles, tanagers, and other birds that migrate among the Americas throughout the year.

For the research, an international team of scientists used the Cornell Lab of Ornithology’s global citizen science database, eBird, to calculate how to sufficiently…

Amsterdam: Part III

Why Evolution Is True

I forgot to mention the ubiquity of bicycles in Amsterdam, but of course it is the first thing one notices on the streets. Bikes are everywhere and most everyone rides one: not ten-speeds or fancy bikes, but solid, sturdy ones designed for horizontal transportation. (You don’t need gears in such a flat country.) Below is the daily sight outside the Central Station in Amsterdam, and this is only a small fraction of bikes parked there, presumably for the day.

It’s a lot easier to get hit by a bike than a car, as Americans aren’t used to looking for bikes, but bike lanes are on every street (sometimes resembling sidewalks) and the cycles come whizzing by. I’ve had a few close shaves.

Below is the Royal Palace of Amsterdam, standing in Dam Square and completed as a town hall in 1655. The exterior is yellow sandstone (now stained with…

Copy, precedent, inspiration

Architecture Here and There

A friend recently revealed in a comment to my blog post “Cranston’s Hall Free Library” that Cranston’s William Hall Free Library, of 1927, must have been inspired by architect Albert Kahn’s William Clements Library, at the University of Michigan in 1923. Inspired is the word I would use. A crank who understands little of architecture might say that one architect copied the other’s work. (William Henry Hall, founder of the Cranston library, is apparently no relation to its architect, George Frederick Hall.)

“Copied the past” is a slur that modernists often use to denigrate the creativity of new traditional architecture whether it actually resembles a particular old building or not. Since the past in this case reached entirely four years back into history, the proper word is inspired. Or…

Fighting Climate Change With Ecosystem Restoration

Throughout the history of this site we’ve focussed on accentuating positive steps in conservation, while also pointing out the negative forces with the intention that knowledge is power that leads to action.

We applaud the UN Environment Assembly for pressing further into the remaining window of opportunity to restore ecosystem health.

New UN Decade on Ecosystem Restoration to inspire bold UN Environment Assembly decisions

The UN Environment Assembly in Nairobi, Kenya, is the world’s leading decision-making forum. From 11 to 15 March 2019, it will be considering how best to improve outcomes for people and planet. Ecosystems will be high up on the agenda.

The timing looks good. The UN Decade on Ecosystem Restoration 2021-2030, declared on 1 March 2019 by the UN General Assembly, aims to massively scale up the restoration of degraded and destroyed ecosystems as a proven measure to fight climate change…

गैलीलियो गैलीली

विज्ञान विश्व

गैलीलियो गैलीली एक इटालियन भौतिक विज्ञानी, गणितज्ञ, खगोलशास्त्री और दार्शनिक थे; जिन्होने आधुनिक वैज्ञानिक क्रांति की नींव रखी थी। उनका जन्म 15 फरवरी 1564 को हुआ था, तथा मृत्यु 8 जनवरी 1642 मे हुयी थी।

गैलीलियो गैलीली की उपलब्धियों मे उन्नत दूरबीन का निर्माण और खगोलिय निरिक्षण तथा कोपरनिकस के सिद्धांतो का समर्थन है। गैलीलियो को आधुनिक खगोलशास्त्र का पिता, आधुनिक भौतिकि का पिता, आधुनिक विज्ञान का पिता के नामो से सम्मान दिया जाता है।

“गैलेलियो, शायद किसी भी अन्य व्यक्ति की तुलना मे, आधुनिक विज्ञान के जन्मदाता थे।” – स्टीफन हांकिस

समरूप से त्वरित पिंडो की गति जिसे आज सभी पाठशालाओ और विश्वविद्यालयो मे पढाया जाता है, गैलीलियो द्वारा काईनेमेटीक्स(शुद्ध गति विज्ञान) विषय के रूप मे विकसित किया गया था। उन्होने अपनी उन्नत दूरबीन से शुक्र की कलाओ का सत्यापन किया था; बृहस्पति के चार बड़े चन्द्रमा खोजे थे(जिन्हे आज गैलेलीयन चन्द्रमा कहते है) तथा सूर्य धब्बो का निरिक्षण किया…
