Why Swiss cheese has holes?

cheese
Standard

Who doesn’t like cheese except Jerry?, since he loved it ❤
But as shown, he loved a special kind of cheese with holes, popularly known as Swiss cheese.

So why this cheese has holes?

Actually in a late stage of cheese production, a special bacteria releases carbon dioxide gas. The carbon dioxide slowly forms bubbles that develop the holes or also known as “eyes”. Incidentally this is the reaction that gives our cheese its nutty and sweet flavor.

But story doesn’t ends here as per Swiss researchers.
They propose that particulate matter (minute separate particles) may also play a role in the holes’ development and that modern sanitization eliminated debris (such as hay dust in the milk) which played a role in reduced hole size in Swiss cheeses.

Historically, the holes were seen as a sign of imperfection and cheese makers originally tried to avoid them by pressing during production. But in modern times, the holes have become an TSP of the cheese.

In general, the larger the eyes in a Swiss cheese, the more better the flavor because a longer fermentation period gives the bacteria more time to react.

 

Why a boxing ring is a square?

boxing ring
Standard

While growing up (90s kid 🙂 ) we have watched several boxing & WWE matches but most of us never wondered why fighting ground is termed as ‘ring’?

Actually since the ancient times, boxing contests were fought in a roughly drawn circle on the ground. Nobody gave much though about the ground shape, as all were interested in the brawls. Thus the name ring continued up being associated in the modern era.

But not until 1838, when the first square ring was introduced by the Pugilistic Society. That ring was specified as 24 feet (7.3 m) square and bound by two ropes. For these and other reasons, the boxing ring is commonly referred to as the “squared circle”.

Incidentally, many boxing championships have involved experimenting with the shapes like octagon.

So why square shape?

The answer lies in the fact that squares are easier to construct and tend to be more stalwart and offer greater flexibility and support. For instance, although CDs and pizzas are round, CD cases and pizza boxes aren’t.

 

Why clothe particles gets stuck in belly button?

belly
Standard

Many times you must have observed some sort of fuzzy substance stuck in your belly button.  The term is belly button lint, my friend. But why it is caused and why only near the belly button.

Well the credit goes to research done by Austrian chemist Georg Steinhauser.
As per him, firstly, the hairs around the navel have very minute scales that act a bit like hooks that latch onto clothe fibers.

Then secondly, those hairs tend to grow in circular patterns around the belly button, leading to the optimize the collection.

Steinhauser tested his hypotheses by shaving his belly. He learned that shaving the belly does indeed lead to a lint-free belly button.

However some also think that rubbing of navel hairs and clothing contributes to a build-up of static electricity, resulting in the collection of clothing fibers and to a lesser extent, dead skin cell. But no solid grounds for that yet.

Why a chocolate bar can kill your Dog ?

dog
Standard

Dogs are known for eating things when they are not supposed to, especially when they are young as puppies and love to explore and chew around any likable thing in proximity. But few of the common human foods may prove fatal.

p.PNG

Like one of our favorites, ‘the Chocolate’,  which is derived from the roasted seeds of Theobroma cacao, which contains two toxic ingredients to your dog: caffeine and theobromine.

As humans, we can easily metabolize theobromine in controlled dosage, but canines such as dogs and cats, process it much slowly, allowing it to build up to toxic levels in their system.

toxic

In other words, for a 70 kg adult human, you’d have to eat >7 kgs of dark chocolate to get close to lethal level. But a small dog will get sick and potentially die from just one bar of dark chocolate. Here’s a calculator  which you can refer to: Chocolate Toxicity Meter | petMD .

And not only chocolates but even grapes, raisins, coffee, caffeine, Xylitol (artificial sweetener), Onions, garlic, Alcohol, Macadamia nuts etc. falls into this category for them.

What should I do if my dog has eaten chocolate?

pup

If you find out that somehow your dog ate chocolate, urgent treatment might be needed depending on the dosage. So do not panic and contact your vet (keep it on speed-dial) as soon as possible for advice.

Meanwhile check for symptoms like vomiting, diarrhea, increased body temperature, rapid breathing etc, which you can brief along with type of chocolate and its dosage.

Hence to be safe, it’s best not to give them any.


 

What’s that ‘click’ sound in my camera?

shutter
Standard

Ever wondered what’s that ‘click’ sound every time you snap a picture via your DSLR ?

Its because your camera has shutter, and the electro-mechanical mechanism that moves and stops the action of the camera’s shutter makes that ‘click’ sound. Though most mechanisms make some sound because of the friction and the impact of a sudden start and stop.

shutter

Ok, so why smartphones and similar devices have that sound, do they also have shutter ?

No. People generally prefer a sound cue to know when the photo is done. Hence phones have that ‘click’ sound when they take a picture, even though they do not have an actual shutter.

Usually smartphones do not use physical mechanisms while capturing, but instead they just have an electronic charge-coupled devices constantly capturing visual data and ‘freeze‘ that capture to grab a shot. These cameras often have an option to have an artificial ‘shutter sound’ played by a speaker so that the photographer and/or subject know that the photo was captured.

smartphone

Thus that fake shutter-sound helps your friends know how long they should try their best, and you get your best moments 🙂 .

But it should also be noted that these shutter sounds are not legal in some countries and some places, especially inside holy places, Museums etc. Even in some, they don’t allow using flashes.

If black box in an Airplane is indestructible, then why don’t they make the whole plane of the same material?

black plane
Standard

The construction of the Digital Flight Data Recorder and Cockpit Voice Recorder boxes is military grade. And they are virtually indestructible.

But there have been many cases where the impact was so strong that even the black box couldn’t sustained damage. Still, why not built an airplane using the ‘strengthening’ concept, isn’t the stronger the better.?

blackb

NO ! since as its well known that, its not the fall that kills you, its the sudden stop.
An indestructible aircraft may survive that sudden stop but no human could.

Black boxes are placed in protected locations near the rear of the airplane and, unlike humans, they are designed to survive accelerations up to several hundred g-forces.

Passengers don’t die because the plane is not strong enough.
Passengers die because unlike black boxes, passengers’ bodies are not strong enough to survive the rapid deceleration, smoke and fire that ensue in a crash.

falling.png
Along with carry-on bags, laptops, food trolleys etc some of which may hit you while traveling at speeds of several hundreds of kmph relative to your body.

Hence the best way of protecting airplane passengers is to avoid crashes in the first place. Task at which our technicians and engineers are getting better each day passing.

It is remarkable how the number of aircraft accident fatalities has not significantly increased in the past 50-60 years despite the fact that air-traffic has increased by a factor of a significant margin !
