Vertue Poem By George Herbert

Vertue


   - By George Herbert


Sweet day, so cool, so calm, so bright, 
The bridal of the earth and skie; 
The dew shall weep thy fall to-night, 
                            For thou must die. 

Sweet rose, whose hue angrie and brave 
Bids the rash gazer wipe his eye: 
Thy root is ever in its grave, 
                             And thou must die. 

Sweet spring, full of sweet days and roses, 
A box where sweets compacted lie: 
My music shows ye have your closes, 
                                  And all must die. 

Only a sweet and virtuous soul, 
Like season'd timber, never gives; 
But though the whole world turn to coal, 
                                      Then chiefly lives.

Jordan Poem By George Herbert

Jordan


      - By George Herbert


Who says that fictions onely and false hair 
Become a verse? Is there in truth no beauty? 
Is all good structure in a winding stair? 
May no lines pass, except they do their duty 
Not to a true, but painted chair? 

Is it no verse, except enchanted groves 
And sudden arbours shadow coarse-spun lines? 
Must purling streams refresh a lover's loves? 
Must all be veil'd, while he that reads, divines, 
Catching the sense at two removes? 

Shepherds are honest people; let them sing; 
Riddle who list, for me, and pull for prime; 
I envy no man's nightingale or spring; 
Nor let them punish me with loss of rhyme, 
Who plainly say, my God, my King.

How Do We Get High Blood Pressure

Blood pressure is the force of our blood that pushes against the arteries. We do need some blood pressure so that it helps the blood to move throughout the body. But at times, the pressure rises more than one needs and stays high over time. This high pressure keeps pushing against the walls of the arteries as the heart pumps blood. In many ways this high rise in the blood pressure can damage our body. This process of the rise in the regular blood pressure and staying high over the time is known as high blood pressure.




High blood pressure is also referred as 'hypertension'. This condition of high blood pressure in one is dangerous as it makes one's heart pump and push more than normal stages. Understand this, the higher one's blood pressure, the greater is the damage risk. High blood pressure needs to be controlled to avoid major damage such as a heart stroke, heart attack or other complications. The situation at times could be fatal.

Symptoms and Causes of High Blood Pressure


Some symptoms of high blood pressure include severe headache, chest pain, tiredness, irregular heartbeat and difficulty in breathing. Some foods that may get you blood pressure higher include intake of salt, packaged foods, frozen food items, heavy creams, etc. Packaged foods and canned foods are the many culprits as they have heavy doses of sodium in it. Foods like canned beans, canned fruits, frozen meats, soft drinks, pastries should be avoided as much as possible.

One can include fresh fruits and vegetables, oatmeal, leafy vegetables, fishes with omega 3s, cow milk and berries to maintain a healthy heart. Other than foods, some other factors that lead to high blood pressure include body temperature, mental state, sleep apnea, over exertion and certain medications or drugs.

How is Blood Pressure Measured?


Blood pressure is measured with an instrument known as the sphygmomanometer, commonly also known as the blood pressure monitor or blood pressure gauge. The blood pressure is measured as systolic and diastolic pressures. Here 'systolic' refers to blood pressure while pumping blood and 'diastolic' means blood pressure when heart is at rest in between beats.

What is a Sinkhole

Also known to be a swallow hole, shake hole, sink or even a doline, a sinkhole is a depression caused in the Earth's surface. These sinkholes that form on the earth's surface do not usually form due to natural process. They can be natural or even man made. These depressions formed in the earth's surface, are due to the dissolution of carbonate rock. And this process is also known to be the Karst process. Sinkholes either could form gradually or may appear sudden.

When water flows underground and starts dissolving the rocks, slowly and gradually sinkholes form. These rocks that dissolve are mostly limestone, salt beds, gypsum or clay.  When rocks start dissolving, small caverns form within the surface. This process carries on over a period of time and the land later caves in. This sudden collapse happens when pressure hits on the earth's surface. Small cracks may emerge to show the beginning of the sinkhole. These small cracks are not dangerous in the beginning. But as the cracks keep expanding and forming a hole, a weight of certain object would make the land cave in.

Sinkholes can differ in size and at times could be big enough to swallow even a house or a swimming pool. The process is so dramatic that it would not give out a warning at times, and suddenly would break out into a big, enormous hole creating chaos.

Tales of Tenali Raman - Tenali Raman And Challenge of The Linguist

Once in the court of King Krishnadevaraya, came a linguist who was known to have traveled all over India and learnt many languages. He conversed with the king's courtiers in many languages fluently. Everyone was thoroughly impressed with him including the king. Now the linguist challenged the court to find out what his mother tongue actually was. The court accepted the challenge and each one of them tried their best to find out the linguist's mother tongue.

One courtier who spoke to the linguist in Bengali said that the linguist was indeed a Bengali. Another one spoke to him in Hindi and declared that the linguist was Hindi.  Each one of the courtier came up with many languages they thought could have been the linguist's actual mother tongue. So no one reached to any solution. The linguist was smart and kept replying without actually revealing any truth. Later on he said to the king, "Dear Lord! There definitely going to be a lot of guessing. But I want more than just guessing".

So now the king turned towards Tenali Raman and asked him to try. Tenali Raman accepted the linguist's challenge. The linguist put a condition in front of the king, that if Tenali Raman failed in proving so, the king would have to reward the linguist with whatever he asked for. The king readily agreed as he had full confidence in Tenali.

Tenali turned to the linguist and said, "Sir, I really appreciate your superior linguistic skills. You indeed are very well read and intelligent. Though you are a master of lots of languages I still believe that you love your mother tongue very much. Please give me a day's time and I promise that I will give my reply tomorrow in this court." The linguist readily agreed and was made to stay in the palace as a royal guest. Tenali Raman himself made sure that all the staying arrangements made for the linguists were comfortable. The linguist was happy with the hospitality he received and enjoyed lovely dinner and soundly retired in his bed.

Tenali Raman had worked out a plan. He waited outside the quarters of the linguist until midnight. He made sure that the linguist was deep asleep. Then he tiptoed towards the linguist's bed. Tenali tickled the linguist slowly with a rough duster. Not once but he repeated the action twice. Suddenly woken from a deep slumber, the linguist started shouting, "Kon Che! Kon Che! Chowkidar! Ma Jagdambe, Raksha karo!" Tenali hid himself behind a cupboard and witnessed the whole act. Once he made sure that the linguist had gone back to sleep, he slid back, went to his house and slept well.

Next day in the court,  everyone including the king anxiously waited for Tenali. Even the linguist was eager about what was going to happen. Tenali Raman entered the court as his usual self and bowed down to the king. The king asked him," Tenali, can you tell us what his mother tongue is?" Tenali calmly answered, "Yes my lord. I can." The King said, "Then tell us," Tenali turned towards the linguist and said, "O Scholar of languages! You are an expert and I bow down to you. But I know your mother tongue is Gujarati. Please confirm it." The linguist replied, "My mother tongue is indeed Gujarati."

Everyone including the king was shocked and surprised to hear it. The king asked, " How did you know, Tenali?" Tenali Raman replied, " Everyone of us love their mother tongue. It is the most dearest to us. Though one may be proficient in many languages, yet he would always turn back to his mother tongue in dire circumstances. I used the same trick with our guest. Last night, I woke up our guest. Being disoriented and frightened he resorted to his mother tongue and shouted in Gujarati."

The linguist came forward and hugged Tenali. He admired his quick wit and praised him. The linguist regarded Tenali as a genius and as usual Tenali Raman proved that to be true.

What is Soundproof Glass

There are numerous occasions when we wish, we were sitting in a room with soundproof glass; especially when we are with friends spilling out secrets. Soundproof glass help us achieve that level of privacy where conversation stay intact with no secrets been revealed to the outside world.

Soundproof glass is a type of glass which refrains sound from penetrating from one side to the other. This could either be from inside to outside or from outside to inside. Such type of glass are used by people who spend time in noisy environment. For example, people living on busy streets or cabins of noisy offices.

How Does Soundproof Glass Work 


Sound in the form of energy pass through various mediums such as solid, liquid or gas. The closer the molecules in the medium, the faster the sound energy pass from one point to another. Since the molecules of a solid medium are closely held, the sound travels faster through it. But when a soundproof glass is installed, it absorbs the sound waves and reduces vibration thus working as a barrier and preventing the sound from passing.

How can Soundproof Glass be Made


A sound proof glass can be made by simply using a thicker glass. The thicker the glass, the stiffer it would be and lesser the vibration. One of the other option to make a sound proof glass is using a material between two panes of glass. One of the most common material used for glass sound proofing is lamination. Lamination of glass is where a thin piece of plastic is placed between two glass panes. This cuts down significant amount of sound and allows noiseless atmosphere. Laminated glass work as the best soundproof glass and best soundproof windows.

What are Waterspouts

Tornadoes that form over water are called as waterspouts. A waterspout is a strong columnar whirlpool that resembles funnel shaped cloud and move over water. At times they form over water and move over land from water. A waterspout could be accompanied by heavy hail storm, lightnings and strong winds. A waterspout has a five part life cycle, which include a dark spot formation on the water surface followed by spiral pattern of water surface and formation of a spray ring along with a development of visible cloud like condensation funnel which finally decays.




Waterspouts can form in an area less than 2 km in width. The column of rotating cloud that is funnel shaped, descends over water. This cloud that develops could be mild or even harmful. Some of the waterspouts formed are strong and usually tornadic in nature. At times these waterspouts could be mild and weak. Such mild waterspouts are caused by different atmospheric pressures and develop in moisture laden environment. Though weaker than a tornado, waterspout can still manage to cause considerable damage to it's surroundings.

Where are waterspouts witnessed?


Waterspouts are witnessed in tropics and subtropical areas. Europe, Australia, New Zealand have common occurrences of waterspout. One of the area which witness waterspouts frequently is Florida Keys with around 400 waterspouts approximately around the world.
