The eggplant and peach emoji are standard code for racy thoughts these days, but people have been using food as sexual innuendo for centuries. In fact, William Shakespeare was a pro at the gastronomic double entendre [insert blushing face emoji here]. The Salt blog asked a Shakespeare expert to help them decode some of the bard’s bawdy food jokes. (And the result is delightful. – Nicole)

Bonus-

George Michael was 23 when he sat for this interview, which has never been broadcast before.

He had just embarked on his solo career after leaving Wham!. During the conversation, George Michael talks about his sexuality and shedding his pop-ballad persona ala Careless Whisper. He reflects on the power of his fame, as he recalls the historical trip Wham! took to play in communist-China in 1985.

Curves of constant width

                                                    Source

The width of a circle is constant: its diameter.

But the circle is not the only shape that holds this pristine title. For instance let’s look at the Reuleaux triangle

Reuleaux triangle

A Reuleaux triangle is a shape formed from the intersection of three circular disks, each having its center on the boundary of the other two.

The Reuleaux triangle is the first of a sequence of Reuleaux polygons, curves of constant width formed from regular polygons with an odd number of sides.

Some of these curves have been used as the shapes of coins

To drill square holes.

They are not entirely square, their edges are fillets i.e the edges are rounded and not sharp.

This animation offers a good insight as to why that is so.

And in china, apparently on bicycles.

The man Guan Baihua shows his self-made multi-angle-wheel bicycle on May 6, 2009 in Qingdao of Shandong Province, China. Guan Baihua spent 18 months to complete this strange bicycle.

Other shapes of constant width

There are other shapes of constant width beside the Reuleaux triangle ( that has been discussed in this post ), a whole bunch of them really. Do take a look at them. ( links below )

I will leave you guys with my favorite one.

Tough as a Tardigrade

Without water, a human can only survive for about 100 hours. But there’s a creature so resilient that it can go without it for decades. This one millimeter animal can survive both the hottest and coldest environments on Earth, and can even withstand high levels of radiation. This is the tardigrade, and it’s one of the toughest creatures on Earth, even if it does look more like a chubby, eight-legged gummy bear. 

Most organisms need water to survive. Water allows metabolism to occur, which is the process that drives all the biochemical reactions that take place in cells. But creatures like the tardigrade, also known as the water bear, get around this restriction with a process called anhydrobiosis, from the Greek meaning life without water. And however extraordinary, tardigrades aren’t alone. Bacteria, single-celled organisms called archaea, plants, and even other animals can all survive drying up.

For many tardigrades, this requires that they go through something called a tun state. They curl up into a ball, pulling their head and eight legs inside their body and wait until water returns. It’s thought that as water becomes scarce and tardigrades enter their tun state, they start synthesize special molecules, which fill the tardigrade’s cells to replace lost water by forming a matrix. 

Components of the cells that are sensitive to dryness, like DNA, proteins, and membranes, get trapped in this matrix. It’s thought that this keeps these molecules locked in position to stop them from unfolding, breaking apart, or fusing together. Once the organism is rehydrated, the matrix dissolves, leaving behind undamaged, functional cells.

Beyond dryness, tardigrades can also tolerate other extreme stresses: being frozen, heated up past the boiling point of water, high levels of radiation, and even the vacuum of outer space. This has led to some erroneous speculation that tardigrades are extraterrestrial beings.

While that’s fun to think about, scientific evidence places their origin firmly on Earth where they’ve evolved over time. In fact, this earthly evolution has given rise to over 1100 known species of tardigrades and there are probably many others yet to be discovered. And because tardigrades are so hardy, they exist just about everywhere. They live on every continent, including Antarctica. And they’re in diverse biomes including deserts, ice sheets, the sea fresh water, rainforests, and the highest mountain peaks. But you can find tardigrades in the most ordinary places, too, like moss or lichen found in yards, parks, and forests. All you need to find them is a little patience and a microscope.

Scientists are now to trying to find out whether tardigrades use the tun state, their anti-drying technique, to survive other stresses. If we can understand how they, and other creatures, stabilize their sensitive biological molecules, perhaps we could apply this knowledge to help us stabilize vaccines, or to develop stress-tolerant crops that can cope with Earth’s changing climate. 

And by studying how tardigrades survive prolonged exposure to the vacuum of outer space, scientists can generate clues about the environmental limits of life and how to safeguard astronauts. In the process, tardigrades could even help us answer a critical question: could life survive on planets much less hospitable than our own?

Don’t play, play - Singlish is studied around the globe

Blogger Wendy Cheng’s Web video series Xiaxue’s Guide To Life and Jack Neo’s Ah Boys To Men film franchise are well-known shows among Singaporeans. For one thing, they are filled with colloquial terms, local references and copious doses of Singlish terms such as “lah” and “lor”.

But they are not merely for entertainment. In recent years, such shows have found a place in universities around the world, where linguists draw on dialogues used in these local productions to introduce to undergraduates and postgraduate students how Singlish has become a unique variety of the English language.

This comes even as concerns have been raised over how Singlish could impede the use of standard English here.

From Italy and Germany to Japan, at least seven universities around the world have used Singlish as a case study in linguistics courses over the past decade. This is on top of more than 40 academics outside of Singapore - some of whom were previously based here - who have written books or papers on Singlish as part of their research.

Southeast Asia before ASEAN: An ASEAN 50 Commemorative Post

Ironically, the region of Southeast Asia was not an Asian concept. It was a Western one. It was perceived primarily through Western eyes as maps were created during the colonial rush to Asia from the 16th to the early 20th century. Hence, it originated as a geographical concept, having been rendered in different words by Western scholarship, especially before the Second World War– words such as “south east Asia”, “southeast Asia” or “south-east Asia.” In the 1930s for example, Southeast Asia was referred to as “Further India” (as if to allude that it’s near the Bay of Bengal, when it is not) or “Asia of the Monsoons” (to refer to the typhoons that frequently ravage the area.” The regional name’s gradual standardization (no longer in the lowercase “southeast”) and the dropping of the hyphen resulted in the name “Southeast Asia.” It was first used and asserted by the Americans, with its U.S. State Department’s “division of Southeast Asian Affairs” and came to be used frequently by the media as the Second World War sparked in the Pacific in 1941.

After the war, the term “Southeast Asia” transformed from a geographic entity to be referred to, to a complex and inchoate group of nations trying to redefine themselves in the world. As each one dropped their colonial fetters and became independent–Indonesia from the Dutch (17 August 1945), Vietnam from the British (2 September 1945), the Philippines from the United States (4 July 1946), Myanmar from the British (4 January 1948), Laos (22 October 1953) and Cambodia (9 November 1953) from the French, Singapore and Malaysia from the British (16 September 1956), Brunei from the British (1 January 1984), with Thailand successfully retaining its sovereignty, each one has tried to redefine their identities apart from their colonial past. With ideological conflicts in parts of Asia, a Southeast Asian integration seems far off. 

*Front page of the Southeast Asia Collective Defense Treaty, 8 September 1954, from the Archives New Zealand. The first attempt at a Southeast Asian cooperation was done in 1954. The United States initiated an alliance that was meant to contain Communism in Asia, and hence, on 8 September 1954, the Southeast Asia Collective Defense Treaty (or the Manila Pact) was signed by only two Southeast Asian countries–the Philippines and Thailand–and joined by the United States, France, Great Britain, New Zealand, Australia, Thailand, and Pakistan. This established the Southeast Asian Treaty Organization or SEATO, where all member countries agree that if any one of them were attacked, all the other member countries would come to its defense–very similar to the North Atlantic Treaty Organization (NATO). But SEATO would end as a failure, for the simple reason that it was seen suspiciously by the rest of Southeast Asia as “a fig leaf for the nakedness of American policy.” Pakistan withdrew in 1972, and France in 1975.

*Philippine President Macapagal, Indonesian President Sukarno and Malaysian Prime Minister Tunku Abdul Rahman signing agreements forming the MaPhiLindo on 5 August 1963 at the Juan Luna Hall of the Department of Foreign Affairs in Manila, from the Malacañang Presidential Museum and Library.

*The Philippine Commonwealth Government-in-Exile proposed a union with Indonesia in 1943, a Pan-Malayan principle reflected in this part of an American 1942 map entitled “Outline of the Post-War New World Map,” a proposed political boundary map at the event that the Allied forces would win World War II. The one marked in blue are the proposed American protectorates of the post-war world.

At almost the same time, another effort was put in at the time of President Diosdado Macapagal. Coming from our commonality as Malays (with the vision of the late President Manuel L. Quezon for a Pan-Malayan nationhood), President Macapagal envisioned a cooperation with other Malay countries. Hence, Macapagal convened a summit in Manila, together with Malaysian Prime Minister Tunku Abdul Rahman and Indonesian President Sukarno, where they signed the Manila Accord on 5 August 1963, addressing controversial issues over North Borneo and Sarawak joining the Federation of Malaysia. The Accord established the Maphilindo, striving for “Asian solutions by Asian nations for Asian problems.” However, this was also seen as a move by the Philippines and Indonesia to stall or halt the formation of the Federation of Malaysia, which eventually happened on 16 September 1963. Indonesia pulled out of the organization, in reaction to Malaysia’s formation which was seen by Indonesia as a threat to its sovereignty, hence the org’s dissolution.

*The five “Founding Fathers” of the ASEAN, signing the Bangkok Declaration, also known as the ASEAN Declaration, on 8 August 1967. From the ASEAN Archive.

This explains the tensed environment that the five Foreign Ministers of Southeast Asia found themselves in on 8 August 1967 in the Thai Department of Foreign Affairs in Bangkok, Thailand. Carefully, and diplomatically, these representatives from Indonesia (Adam Malik), Malaysia (Tun Abdul Razak), Singapore (S. Rajaratnam), Philippines (Narciso Ramos) and Thailand (Thanat Khoman), sat down together, chose their words carefully, patiently wrestled on their issues through dialogue, and bravely met on common ground. It entailed a larger vision, one that did not only concern each of their nation’s concerns, but one that gave space to regional unity in spite of their differences. Rajaratnam said to his counterparts on that day:

We must think not only of our national interests but posit them against regional interests: that is a new way of thinking about our problems. And these are two different things and sometimes they can conflict. Secondly, we must also accept the fact, if we are really serious about it, that regional existence means painful adjustments to those practices and thinking in our respective countries. We must make these painful and difficult adjustments. If we are not going to do that, then regionalism remains a utopia.

“Painful adjustments” indeed. After all was said and done, the five Foreign Ministers, representing their heads of state, after months of negotiations and compromise, finally and unequivocally signed the two-page ASEAN Declaration, establishing the Association of Southeast Asian Nations, and committing themselves to resolving disputes by peaceful means and through hard but committed mutual accommodation. Bereft of the colonial baggages of the previous southeast asian intergovernmental organizations, it was Southeast Asian, from the inception of the idea to its founding. 

The founding of the ASEAN in 1967 led to the diplomatic reconciliation between Malaysia and Indonesia, and Malaysia and Singapore. And while a year later, Malaysia temporarily severed its diplomatic relations with the Philippines due to claims over Sabah, this kind of issues never impeded the commitment the two nations have in ASEAN, so was with the other member-states with similar problems. Since then, ASEAN has grown into a 10-member-state organization. This probably explains why ASEAN is “the most successful inter-governmental organization in the developing world today.”

In the occasion of the Philippine Chairmanship of the ASEAN and its 50th founding anniversary, Happy ASEAN 50th!

*Post-script: The deafening silence of the Philippines with its unprecedented win in the arbitration ruling in the ASEAN meetings ought to make people question our foreign policy. Insisting on our sovereign rights over our EEZ does not mean war-mongering. Vietnam, on the other hand, the nation that defeated the United States in the Vietnam War, still insists the rule of law thus challenging Chinese encroachment diplomatically. It exemplifies a fair and “independent foreign policy.” The Philippines should follow Vietnam’s example.

A basic schematic of why the Korean alphabet is so cool, from Wright House: 

Unlike almost every other alphabet in the world, the Korean alphabet did not evolve. It was invented in 1443 (promulgated in 1446) by a team of linguists and intellectuals commissioned by King Sejong the Great.

In the diagram [above], the Korean consonants are arranged into five main linguistic groups (one per row), depending on where in the mouth contact is made. Notice that there is a graphic element common to all the consonants in a particular row. The first consonant in each row is the most basic and is graphically the simplest; this representative consonant for each group is the building block for the other characters in that group. Certain of these modifications are systematic, and yield similarly modified characters in several groups, such as adding a horizontal line to a simple consonant (a “stop” consonant–such as t/d or p/b–rather than a nasal consonant) to form the aspirated consonants (those made with extra air) and doubling simple consonants to form “tense” consonants (no real equivalent in English).

Notice that the five representative consonants (the ones in the first column in the upper part of the diagram) are also depicted in the drawings that make up the lower part of the diagram showing the relevant part of the mouth involved. Ingeniously, each of these representative consonants is a kind of simplified schematic diagram showing the position of the mouth in forming those consonants.
