Russian doctor Osip Krichevsky first produced powdered milk in 1802. It is made by drying or dehydrating milk until it forms a fine white powder. This can be achieved either by spraying a fine mist of milk into a heated chamber or by adding the milk in a thin layer to a heated chamber or by adding the milk in a thin layer to a heated surface of, from which the dried milk solids can be scrapped off. Freeze drying is now used because it conserves more nutrients and the milk can be fortified to improve its nutritional value. The resulting powder can then be stored for long periods, because the dry environment means it is less prone to bacterial contamination that would spoil fresh milk. As well as its potential for long term storage, powdered milk has several practical advantages over fresh milk. In the developing world, its relative light weight and the fact that it does not need refrigeration , mean that it is easy to transport over long distances, without the need for expensive refrigerated trucks.
Powdered milk. has found an additional use in modern science in a technique for separating proteins called Western Blotting in the process, the protein rich milk is used to block inappropriate binding of the antibodies used and therefore produce a much clearer result in experiments.

How We Get Powdered Milk
How we Get First Oven
Just as the Egyptians brought the prehistoric era to an end in about 3000 B. C. E, they appear to have produced the first closed oven . It was invented as a way to satisfy the demand for better bread . Flatbread had been around for approximately 5000 years, but Egyptians ovens enabled the bakers to produce bread with yeast, bread was no longer flat, it was rising.
A traditional Oven is one of the simplest inventions, it traps heat within its walls in order to cook the food placed within. However, when considering the timing of the invention of the ovens .
It is necessary to consider the agricultural advances that resulted in the need for it. After the last ice age around 10000 years ago, the land began to warm up from its frostbitten slumber and gradually provide its inhabitants with grain and other foods from the plant species that had been hibernating beneath the ice. Our predecessors may have been a little slow in responding to these new sources of nutrition but as demonstrated by the Egyptian bakers, they eventually got there. Open tandoor ( cylindrical clay brick) ovens have been found in Mohenjo-Daro, the indus valley city settlement also dating from 3000 B.C. E . However, it was the ancient Greeks who developed front loaded and portable ovens, and used them to turn bread making into a profitable venture.
How we Get Alcoholic Drinks
Alcoholic Drinks
The accidental fermentation of a mixture
of water and fruit in sunlight is thought to
have led to the first discovery of an
alcoholic drink by a prehistoric people.
Evidence of intentionally fermented
beverages exists in the form of Stone
Age beer jugs dated as early as the
Neolithic period (10,000 B.C.E.) . Other
jugs have been excavated in Southwest
Asia and North Africa.
Alcoholic beverages have been an integral
part of many cultures, used as a source
of nutrition, in meals for celebration, and
also in religious ceremonies. Alcohol can
give a sense of well being, but also acts
as a depressant, lowering behavioural
inhibitions.
Alcohol consumption became a status
symbol for the wealthy people. During the
Middle Aged , conctions were distilled to
produce spirits. Alcohol has also served
as a thirst quencher when water was
polluted. In the 1700s home brewing
process were replaced by commercially
made beer and wine , which became
important for the economies of Europe.
Beer was the first known alcoholic
beverage, but many others have been
produced since then. The Chinese are
thought to be yellow wine 4,000 years
ago. In Europe the monasteries owned
the best vineyards., French monks
produced a sparkling wine, which was
named after the Champagne region of
France. Brandy is supposed to have been
accidentally discovered when a Dutch
trader tried boiling wine " to remove the
water and save Cargo space,".
Attitudes to alcohol consumption
have varied over time and different
countries have limited the hours when
drinking establishment are open, or even
banned the sale of alcohol altogether, as
Americans did in the Prohibition, between
1920 and 1923.

How we start clothing ?
Clothing Around 400,000 years ago, Homosapiens devised a solution to protect the vulnerable naked human body from the environment -- clothes. Anthropologists believe the earliest clothing was made from the fur of hunted animals or leaves creatively wrapped around the body to keep out the cold, windand rain.Determining the date of the invention is difficult. Although sewing needles made from animal bone dating from about 30000 B.C .E have been found by archeologists.However genetic analysis for human body lice reveals that they have evolved 107,000 years ago, but further investigation placed their evolution a few hundred thousand years earlier.
Clothing has changed dramatically over the centuries although its ancient role as an outward indication of the status, wealth and beliefs of the wearer is as ever. During the industrial revolution the textile industry was the first to be mechinized, enabling increasingly elaborate designs to be made at a faster rate. In the twenty first century mechanisation has allowed sophisticated practical clothing to be devised to protect us from dangers such as extreme weather, chemical, insects and outer space. Without clothing we would not have been able to explore our world and the surrounding universe to the extent that we have
.लगभग 400,000 साल पहले, होमोसैपियंस ने पर्यावरण से कमजोर नग्न मानव शरीर की रक्षा के लिए एक समाधान तैयार किया - कपड़े। मानवविज्ञानी मानते हैं कि शुरुआती कपड़े शिकार किए गए जानवरों के फर से बने होते हैं या ठंड, हवा की बारिश से बचने के लिए शरीर के चारों ओर रचनात्मक रूप से लिपटे रहते हैं। आविष्कार की तारीख तय करना मुश्किल है। यद्यपि लगभग 30000 ई.पू. से जानवरों की हड्डियों की डेटिंग से बनाई गई सुइयों को पुरातत्वविदों द्वारा पाया गया है। मानव शरीर के जूँ के लिए आनुवंशिक विश्लेषण से पता चलता है कि वे 107,000 साल पहले विकसित हुए हैं, लेकिन आगे की जांच ने कुछ सौ साल पहले उनके विकास को रखा।
कपड़े सदियों से नाटकीय रूप से बदल गए हैं, हालांकि पहनने वाले की स्थिति, धन और विश्वासों के एक बाहरी संकेत के रूप में इसकी प्राचीन भूमिका हमेशा की तरह है। औद्योगिक क्रांति के दौरान टेक्सटाइल उद्योग सबसे पहले किया गया था, जो तेजी से विस्तृत डिजाइनों को तेज दर पर बनाने में सक्षम था। इक्कीसवीं सदी में मशीनीकरण ने हमें चरम मौसम, रासायनिक, कीड़े और बाहरी स्थान जैसे खतरों से बचाने के लिए परिष्कृत व्यावहारिक कपड़ों की अनुमति दी है। बिना कपड़ों के हम अपनी दुनिया और आसपास के ब्रह्मांड का पता लगाने में सक्षम नहीं होते।
