At The Very Centre Of The Image Above Is Something Incredible - A Single, Positively-charged Strontium

At the very centre of the image above is something incredible - a single, positively-charged strontium atom, suspended in motion by electric fields.

Not only is this an incredibly rare sight, it’s also difficult to wrap your head around the fact that this tiny point of blue light is a building block of matter.

The image was captured by physicist David Nadlinger from the University of Oxford, and it’s been awarded the overall prize in the UK’s Engineering and Physical Sciences Research Council photo competition.

To give you a little perspective on the size of this set-up, the atom is being held in place by electric fields emanating from those two metal needles on either side of it.

The distance between them is about 2 millimetres (0.08 inch).

The atom is being illuminated by a blue-violet laser. The energy from the laser causes the atom to emit photons which Nadlinger could capture on camera using a long exposure.

The whole thing is housed inside an ultra-high vacuum chamber and dramatically cooled to keep the atom still. Nadlinger took this photo through the window of the vacuum chamber.

Repair Cafés

Repair Cafés

Repair Cafés are free meeting places and they’re all about repairing things (together). In the place where a Repair Café is located, you’ll find tools and materials to help you make any repairs you need. On clothes, furniture, electrical appliances, bicycles, crockery, appliances, toys, et cetera. You’ll also find expert volunteers, with repair skills in all kinds of fields.

Visitors bring their broken items from home. Together with the specialists they start making their repairs in the Repair Café. It’s an ongoing learning process. If you have nothing to repair, you can enjoy a cup of tea or coffee. Or you can lend a hand with someone else’s repair job. You can also get inspired at the reading table – by leafing through books on repairs and DIY.

There are over 1.500 Repair Cafés worldwide. Visit one in your area or start one yourself!

Meera Bai;

Meera Bai;

“One night as I walked in the desert the mountains rode on my shoulders

and the sky became my heart,

and the earth - my own body, I explored.

Every object began to wink at me, and Mira wisely calculated thinking,

My charms must be at their height

now would be a good time to rush into his arms,

maybe He won't drop me so quick.”

प्रिय लिखकर

लिखा बीच में क्या यह तुमको पढ़ना है

likha beech mein kya yeh tumko padhna hai

what I've written in the middle that you'll have to read

कागज़ पर मन की परिभाषा का अर्थ समझना है

kaagaz par man ki paribhasha ka arth samjhna hai

you'll have to understand the definition of my heart written on the paper

प्रिय लिखकर

जो भी अर्थ निकालोगी तुम वह मुझको स्वीकार है

jo bhi arth nikaalogi tum woh mujhko swikaar hai

whatever meaning you'll decipher is welcomed by me
