the semantics of the senses

Yummy! Delicious! 

Ugh! Yucky!

These are some of the first words we hear (or exclaim) as we take our first taste of food. As we continue munching on it, we dissect what makes the food pleasurable or revolting in our mouths. How do aromas, flavours, and textures contribute to the sensory experience of the food? 

As we ponder how to describe the food, we initially come up with textural dichotomies like hard or soft, sticky or slick, rough or smooth. At the same time, we figure out the individual flavours of the food that sum up to the overall taste; how saltiness, bitterness, sweetness, sourness, and umami contribute to the roundness of the food; how the aromas leave an aura to the dish, heightening the sensory experience.

Often, this is where we hit a dead end. For instance, without further prodding, we stop describing food at "hard". What do we mean by "hard" food? Is it firm? Is it tough? Does it even matter? After all, the antonym of these three adjectives (to a person who uses English as a second language) is "soft". 

Are they really the same though? Jello can be described as firm  and overcooked kangaroo meat may be tough but they certainly aren't hard as rock candy. Hence, on a deeper level, these three descriptors of the difficulty of biting onto food aren't equivalent at all. No wonder that we, consumers, have difficulty describing what we like and do not like to people who develop food products. 

This is where semantics comes into play. Semantics is the field of linguistics that looks into the meanings of words. And the meaning of words arise based on the cultural experience of the users of these words. Do we have enough words to describe what we perceive through our senses? I would think that we do, we just have to find them... and not confine ourselves to the English dictionary. Just like the word "umami". It's not English; it's a Japanese word that describes the savoury sensation of food, perhaps that feeling of warmth and comfort after drinking a bowl of hot soup (that is actually perceived on the tongue).

For developing food with superior quality, finding these descriptors and then figuring out what makes the food that way is a real challenge. It's time to look outside the rigidity of the sciences and to explore the  flexible world of linguistics.

my top 10 life lessons from Suits season 1

I enjoy watching this series on TV called "Suits". It follows a strong mentor-mentee relationship. Harvey Specter (played by Gabriel Macht), one of the best lawyers in the city, gives valuable lessons to his associate, Mike Ross (played by Patrick J. Adams), the lawyer without the law degree. I find myself taking notes (and tweeting them) as I watch the different episodes.
While waiting for the July 1 premiere of the second season of Suits on Jack TV, I list down the top ten lessons that I gleaned from watching the first season of series. It's not surprising that many of them came from the great Harvey Specter. There are few things in there that came from Mike and Harvey's arch-nemesis, Louis Litt (played by Rick Hoffman), as well.
NOTE: if these sound like a lecture, it's because these are notes I write to myself for when I need them... and to whoever is reading this list.

Here we go:

Federico de Vera's brand of beauty at the Ayala Museum

On my latest visit to the Ayala Museum this year, I was able to catch the exhibit curated by Federico de Vera. I haven't heard of him, most likely because I'm not part of the art circles. I'm just an occasional museum hopper who likes to visit beautiful art pieces. This time, I was about to learn what beauty is, in the eyes of famous curator de Vera.
I was blown away by how he presented art pieces he picked up from other art collectors. Some of these pieces I've seen in other museums before. BUT, these are presented in a more striking manner... Instagrammable being the first word that comes to my mind. Spot lighting and subtle backgrounds really make the artworks pop. Walking through the different sections of the exhibit, I kept saying wow to myself. I liked the way that the curator presented every piece... he succeeded in putting the best face of each piece on display. There was a sense of meticulousness in the detail... not just dumping pieces together on a table or…


Back in college, I used to play with the UPLB Ethnomusemblia, a group of students who liked to play traditional Filipino music as live accompaniment to the UPLB Filipiniana Dance Troupe, those students who performed Filipino local dances. Tribal music was what I learned with the group: music filled with textures of the sounds from kulintang and agong; the resonating sounds of simultaneously beaten gangsa; and the deep tones from the dabakan. However, I never learned how to play stringed instruments that are part of the rondalla. I attempted the banduria but to no avail. That's why I never learned to play the music for the tinikling; instead, I contented myself with listening to the rondalla people play the lively song.

Tinikling is the national dance of the Philippines. In this lively dance, the man and the woman imitate the movements of a tikling, a bird found in the country, over two parallel bamboo poles set horizontally on the floor. The dance is made more challenging as the b…
