This is great :) My favorite is proof by ghost reference, what is yours?

On this day, 6th May 1840, the first adhesive postage stamp in the world, the Penny Black, came into official use in Great Britain.

It depicted a portrait of Queen Victoria and stamps continued with her image until her death in 1901.  All British stamps still show the monarch somewhere on the design. They are the only postage stamps in the world that do not indicate a country of origin; the monarch’s image symbolises the United Kingdom.       

The Penny Black lasted less than a year. A red cancellation was hard to see on the black design and the red ink was easy to remove; both made it possible to re-use cancelled stamps. In February 1841, the Treasury switched to the Penny Red and began using black ink for cancellations instead, which was more effective and harder to remove.

The State Library of New South Wales holds significant postage stamp collections, which include a number of penny black stamps -

Ancient Egypt as seen through western eyes is mostly monumental and remote, distant in time and overwhelming in scale. The earliest western illustrations and photographs of Egypt regularly emphasized size and stillness; romantic artists of the nineteenth century frequently placed people in vast desert landscapes—the figures small and insignificant, lost in the deep antiquity of an unchanging land.

This grand vision of Egypt is so firmly fixed in western culture that discovering a different interpretation comes as a revelation. Fortunately, the Brooklyn Museum Wilbour Library of Egyptology owns a rare treasure that offers an alternate view. A Nile Voyage of Recovery, by Charles and Susan Bowles was published in Japan by Hasegawa Takejirō [長谷川武次郎 in 1896. Hasegawa was Japanese publisher active in the late nineteenth century who specialized in books in European languages, often for Japan’s tourist trade and resident foreign community, which included many English missionaries. The volume is part of the Red Cross series. During this time period, the Red Cross was active in setting up libraries and creating publications for soldiers in hospitals and recovery centers around the world.

Many of Hasegawa’s early books were in the form of chirimen-bon (ちりめん本) or crêpe paper books. Chirimen, or crepe, is a Japanese textile with a soft, slightly wrinkly texture that’s often used in Japan to make kimonos, or for wrapping cloth. Hasegawa used the material to produce small, delicate books that can be held in the hand with the pages unfolding easily like fabric.

Our chirimen-bon of A Nile Voyage of Recovery is illustrated with graceful, color woodblock prints of Egyptian scenes and adorned with exquisite typography. The images are gentle and intimate, emphasizing details and delicate color. Even a portrayal of the great pyramid gives more page-room to rays of light and the sun rather than the monuments. The Sphinx does not dominate; it’s rather an integral part of the landscape.

Why study this human-scale Egypt? Because the purpose of art after all is to unsettle the conventional view—and whenever we see the world through other eyes, we see something new.

Top 10 Most Uncomfortable Physics Facts

While physics can show us amazing things about our universe, it doesn’t always agree with how we think things should work. Sometimes, physics can be very counter-intuitive, and often unsettling. So, here’s my list of physics facts that can be a bit unnerving.

10: Weight doesn’t matter

If it wasn’t for air resistance, everything would fall at exactly the same speed. If you let go of a hammer and a feather from the same height at the same time  on the Moon, they would hit the ground simultaneously. 

9: Gyroscopic precession

It doesn’t matter how much you know about physics; gyroscopes are weird. The way they seem to defy gravity makes you rethink everything you know about physics, despite being fairly simple toys. Still, it’s all just Newton’s laws of motion.

8: Neutrinos and dark matter

We like to think that we can interact with most of the world around us, but this couldn’t be further from the truth. Neutrinos and dark matter are passing through your body right now, as if you weren’t even there. The fact that 65 billion neutrinos pass through each square centimeter of your body every second is weird enough, who knows what we’ll learn about dark matter.

7: Photons are particles

Light travels like a wave, but can only interact like a particle. It can interfere and have a frequency, but it can only take and give energy in discrete quantities. It behaves like nothing else in our macroscopic world, and can be very difficult to imagine.

6: Electrons are waves

We’ve established how photons act like waves and particles, but surely massive particles act normally. Nope! Even electrons have wave-like properties. In fact, everything acts like a wave! Except these waves come in discrete quantities, which we’ll call particles. This won’t get confusing.

5: E=mc^2

Einstein’s most famous contribution to physics states that matter is simply another form of energy, which has very profound consequences. A wound-up Jack-in-a-box would weigh ever so slightly more than a released Jack-in-a-box, due to the potential energy stored within.

4: Time is relative

The core of special relativity states that time passes differently for different observers. If you took a trip to Alpha Centauri at 99% the speed of light, everyone on Earth would see the trip take 4.4 years, while you would only experience 7.5 months. Time travel is real!

3: The (not so empty) vacuum

Something can be created from nothing, as long as it goes right back to being nothing quickly. In seemingly empty space, particles pop in and out of existence all the time as a result of the uncertainty principle. Not to mention, space is inflating at an accelerated rate due to “dark energy”. To the vacuum, the law of conservation of energy is more of a suggestion.

2: c is the fastest speed

Another important point in special relativity is that nothing could ever go faster than light. This doesn’t sit well with a lot of people, but the math doesn’t lie. To even get something with mass to travel at the speed of light would require infinite energy. Even if you somehow get around this, there are just too many mathematical problems with superluminal travel. Like it or not, the universe has a speed limit.

1: The cat is dead and alive

How could it not be this? The nature of quantum mechanics allows for objects to take on two seemingly contradictory states in a ‘superposition’. An electron can be in two places at once, or in a more extreme example, a cat can be both dead and alive. Of course, this weird property goes away once someone makes an observation. It’s as if there are tiny physics trolls messing with nature whenever we’re not looking.

Of course, there’s plenty more unsettling physics facts, like the space-bending nature of general relativity, or the “spooky action at a distance” that is quantum entanglement, but these are my top 10. I’d like to hear any unsettling physics facts you think I’ve missed, though!

How Humans Change Space Itself

It’s no surprise that humans influence the surface of our planet, but our reach can go farther than that. Humans affect space, too.

We know storms from the sun can naturally change the space environment around Earth, which can have an impact on satellites and power grids.

Scientists now know that Cold War era nuclear tests in the 1950s caused similar effects.

Particles around Earth are organized into layers known as radiation belts. These 1950s tests created a temporary extra layer of radiation closer to Earth. 

The effects of this could be seen all around the world. Aurora appeared at the equator instead of the poles, utility grids in Hawaii were strained, and in some cases, satellites above test sites were affected. 

Some types of communications signals can also affect Earth’s radiation belts. 

Very low-frequency waves, or VLFs, are used for radio communications. They are often used to communicate with submarines, because these waves can penetrate deep into the ocean. 

The waves can also travel far into the space environment around Earth. When these waves are in space, they affect how high-energy particles move, creating a barrier against natural radiation.

The outer edge of this radio-wave barrier corresponds almost exactly the inner edge of Earth’s natural radiation belts – meaning it could be human activity that at least partly shapes this natural radiation around Earth.

Types of mooncakes

Right now(is festival for chinese singaporeans) is the mid-autumn festival. According to the ancient Chinese legend, the story of Chang Er, the wife of a merciless king who downed the elixir of immortality he had intended to drink, to save her people from his tyrannical rule.The tale goes that she ascended to the moon after that, and has been worshipped by the Chinese as a Moon Goddess ever since. 

Making and sharing mooncakes is one of the hallmark traditions of this festival. In singapore, we have main five different chinese dialect group(hokkien,teochew,hakka,cantonese,hainanese) so of course, there are five different types of mooncakes.

CANTONESE MOOKCAKE

This is the most common style of mooncakes sold by bakeries and hotels. The round pastry, which is about 10cm in diameter and about 4cm thick, comes from south China’s Guangdong province and is also eaten in Hong Kong and Macau. The traditional mooncake is filled with lotus seed or red bean paste with egg yolks inside. 

However, there are the modern snowskin mooncakes which contains anything from durian to champagne. (below are champagne mooncakes)

HOKKIEN MOONCAKE

They were known as Scholar Cakes in the past and given to those taking the Imperial Examination to fill junior and senior administrative positions in the Imperial Court. The filling usually comprises winter melon, tangerine peel and melon seeds. Sesame seeds are sprinkled on the white pastry to make it fragrant.

HAINANESE MOONCAKE

Hainanese ones are filled with dried fruit such as tangerine peel as well as sesame seeds and melon seeds. It has two verision with a salty and pepper version. The.The slightly flaky skin is made with pork lard and salt. According to a blog, they are actually only found in singapore as the story goes that the hainanese community in singapore was very poor and could not afford the normal mooncakes sold so they made their own type of mooncake.

TEOCHEW MOONCAKE

Yam-filled mooncakes with a flaky crust are the most common Teochew mooncakes sold in Singapore. Another type is la gao, which is a steamed black sesame cake. It comes plain or with green bean paste or yam filling. There is also another type of Teochew mooncake, a white disc that looks like a big biscuit and is filled with tangerine peel and sugar, flavoured with five-spice powder and topped with sesame seeds.

HAKKA MOONCAKE

This is actually uncommon and almost unheard of in singapore but moon cakes in Hakka regions of china, apart from common moon cakes, have “five-kernel moon cakes” and a kind of round cake made with glutinous rice flour and sugar, compressed into different size. (I can’t find an exact picture of the hakka mooncake so) 

5 NASA Software Codes You Can Download – For Free!

One of the biggest steps of any mission starts right here on Earth at a computer desk – NASA runs on software, period. Rovers can’t move, spacecraft can’t fly, even rockets can’t blast off without the software codes that run them all.

We’ve compiled hundreds of these powerful codes into one location at software.nasa.gov. And guess what? You can start downloading them right now for free! Here are just a few you can use:  

1. TetrUSS (Tetrahedral Unstructured Software System)

TetrUSS has been used extensively for space launch vehicle analysis and design, like on the Space Launch System, which is planned to take humans to Mars.

You really could say it’s helping us to “blast off.” Outside of NASA, this software has been used to analyze Mars planetary entry vehicles, ballistics and even high-altitude sky diver aerodynamics. Basically if anything has moved through any planetary atmosphere, this software has played a role.

2. KNIFE (part of the FUN3D software and released as a package)

The name may be a bit intimidating, but with good reason – KNIFE packs a powerful punch. 

It was created to help us learn more about the sonic booms that resonate when planes break the sound barrier, but it has also helped develop green energy sources such as wind turbines and techniques to minimize drag for long-haul trucking. Maybe we should re-name this versatile and handy code, “Swiss Army KNIFE?”

3. Cart3D (Automated Triangle Geometry Processing for Surface Modeling and Cartesian Grid Generation)

If software codes went to high school, Cart3D would be Prom Queen. This software is so popular, it is being used in almost every mission area here at NASA. 

Engineers and scientists are currently using it to model everything from advanced drones to quieter supersonic aircraft.

4. FACET (Future Air Traffic Management Concepts Evaluation Tool)

Frequent flyers: this may be your favorite code without even knowing it. FACET was developed to evaluate futuristic concepts in air traffic management, and it has served as a testbed for assessing today’s regular operations. 

To sum it up, this software code helps airports keep planes organized in the air and on the ground.

5. GIPSY-OASIS

GIPSY-OASIS is part of the GPS system to end all GPS systems. It’s so accurate, John Deere used it to help create self-driving tractors.

 How? John Deere already had a navigation system in the works, but it could only be used in certain parts of the world. 

Our ground stations are all across the globe, and our software ensures accuracy down to a few inches. And so, a new breed of tractor was born!  Did we mention this software is free?

These are just a few examples of the software NASA has available for free public and consumer use. To browse the catalog online, check out software.nasa.gov.

In slow motion, vortex rings can be truly stunning. This video shows two bubble rings underwater as they interact with one another. Upon approach, the two low-pressure vortex cores link up in what’s known as vortex reconnection. Note how the vortex rings split and reconnect in two places – not one. According to Helmholtz’s second theorem a vortex cannot end in a fluid–it must form a closed path (or end at a boundary); that’s why both sides come apart and together this way. After reconnection, waves ripple back and forth along the distorted vortex ring; these are known as Kelvin waves. Some of those perturbations bring two sides of the enlarged vortex ring too close to one another, causing a second vortex reconnection, which pinches off a smaller vortex ring. (Image source: A.

The Graduate, 1967.

On this day, 13th February 1743, Sir Joseph Banks was born.

Sir Joseph Banks was a British botanist and naturalist who sailed with Captain James Cook on the Endeavour voyage of 1770.

Joseph Banks was born on 13 February 1743 in London. His passion for botany began at school. From 1760 to 1763 he studied at Oxford University, during which time he inherited a considerable fortune. In 1766, Banks travelled to Newfoundland and Labrador, collecting plant and other specimens. The same year he was elected a fellow of the Royal Society.

In 1768, he joined the Society’s expedition, led by Captain James Cook, to explore the uncharted lands of the South Pacific. The expedition circumnavigated the globe and visited South America, Tahiti, New Zealand, Australia and Java. Banks collected an enormous number of specimens on the way and, on his return, his scientific account of the voyage and its discoveries sparked considerable interest across Europe.

The journal kept by the then 25-year-old Joseph Banks on board HMS Endeavour is one of the State Library’s most significant manuscripts. It records the first Pacific voyage of Captain James Cook from 1768 to 1771. Following the Endeavour’s return to England in 1771, Banks was hailed as a hero. 

The State Library’s Sir Joseph Banks collection includes correspondence, reports, invoices, accounts, maps and watercolour drawings which document the far reaching influence of Banks on the colony. This significant archive containing over 7,000 pages has recently been digitised and now needs to be transcribed. Once fully transcribed the archive will be keyword searchable which will enhance discovery and access to the collection and increase the research potential in this significant archive.
