GoPro or GoPRO Inc is an American Technology Company engaged in the manufacturing of Action Cameras. These cameras are for making stunning dynamic videos in which it captures the dynamic scenes like traveling, mountain climbing and underwater life in oceans. These cameras can take photos, make videos, time lapse videos. Bikers can fix these on their body using the accessories provided.
Latest camera released by GoPro is GoPro Hero 10. It was launched in 16 September in 2021 in India. Camera is available here in India either in stores and also on Amazon and Flipkart. It costs around INR 50000/-. In US it costs around 500$ and in UK around £480.
The major change is the upgradation of the processor. All previous versions used GP1 processor. Hero 10 uses GP2 processor with almost double speed. It shoots 5.3K video with double the frame rate, 23MP photos. Maximum frames per second are 240. It is equipped with HyperSmooth 4.0 video stabilization. It has enhanced low light performance.
It is very lightweight camera . It’s dimensions are 68x50x29 mm and weight is 54 grams.
The camera is connected to cloud and once connected footage can be automatically uploaded to the cloud. Otherwise in such high quality videos the file size of the video would be huge and camera card would be easily become full. Similarly the power consumption would be high. So it is recommended to keep an extra battery with it while outdoors.
The camera is waterproof and is used in under water conditions without any fear with same convenience as on the land or the sky. There are many videos about unboxing on the YouTube. One of the beginner’s tutorials link is given below. It is a very thorough video covering everything from unboxing to hardware explanation to its functions accompanied by video examples.

All communication devices like mobiles and tablets require regular charging because of the continuous use of these devices. Since these devices travel with the owner, every owner desires that the charger should be faster as well as durable. Mostly the chargers that come with the devices are device specific and have limited life time resulting in recurring costs of buying the chargers again and again.
Similarly, in a family individuals have mobiles with different designs and thus every device has its own charger. Users want type of chargers which can be near universal. These could be easily used with iOS, Android operating systems.
There is now an answer to all these requirements. It is MAGFAST Lux & Extreme Charger.
It comes equipped with an MFI-certified charging option for all iOS and Apple devices as well a USB-C and USB-A connection for Androids and other non-apple.
According to the manufacturers, the charger’s cable can withstand up to 25,000 bends, which is possible due to its use of Teflon wiring. What’s more, the charger has three Qi devices at the same time and has a total of 5 separate USB outlets. Qi charging is contactless or wireless charging achieved by induction.

1. Jacinda Ardern:
Prime Minister of Newzealand. She tops the list for the role she played to tackle COVID-19 from spreading in New Zealand. In a nation of 5 million only 2700 cases and 26 deaths. For 6 months she and her cabinet took 20% pay cut.
2. mRNA Pioneers:
COVID-19 vaccines which are largely administered today rely on mRNA. Although mRNA was discovered in 1960, it was in mid 2000 that researchers figured out how to modify the building blocks of those molecules for therapeutic purposes so that mRNA strands could safely interact with the body. Moderna and BioNTech, collaborated with the mRNA Pioneers made it to the list.
3. Daniel H Schulman:

Marie Curie is the shining example of Grit and Patience. She is an example of unerring in her enquiry and never afraid of hard work.
She was born in Warsaw Poland which was under the control of Russia at that time. She left Warsaw for Cracow which was under Austria then. From there she went to France for higher studies and settled there.
Marie Curie is considered the Greatest Scientist. She set a shining example for generations of scientists.
She and her whole family was the family of illustrious scientists.
It is 110 years since Marie Curie became the first person ever to win two Nobel prizes. Marie and her husband Pierre pioneered the study of radioactivity and discovered two new elements, Radium and Polonium. The name Polonium was given as an honour to mark the country Poland her bith place.
The couple shared the Nobel Prize for the radioactivity work with Henry Becqerel who discovered the X-rays. Curie and her husband established the technique to isolate the radioactive elements from ore.
The pair had to process 8000 kg of pitch-blend minerals under horrific conditions to extract tiny amounts( 0.1 gm) of radium!!!!!!!
Their daughter, Irene, also won a Nobel prize in chemistry, and Marie is remembered in the names of universities, institutes, charities and the element curium.
Continuing the subject of dreams, it is pertinent to mention that lucid dreams had helped many to make great discoveries and inventions. Since my subject is chemistry, I will touch upon one such famous dream which laid the foundation for understanding the structure and chemistry of aromatic compounds.
As every one versed with chemistry knows, the benzene is the starting compound of aromatic compounds. Its structure was derived by Kukule’. His full name was Friedrich August Kekulé von Stradonitz.
Benzene was analyzed to have 6 carbon and 6 hydrogen atoms. Existing formula of all the organic compounds did not fit into the structure of benzene and explain its strange properties.
Kukule’ was working on this problem but could not find its solution. Totally engrossed, he fell into a sleep in front of fireplace. He has a dream of the atoms which he described in his own words as follows:
“...I was sitting writing on my textbook, but the work did not progress; my thoughts were elsewhere. I turned my chair to the fire and dozed. Again the atoms were gamboling before my eyes. This time the smaller groups kept modestly in the background. My mental eye, rendered more acute by the repeated visions of the kind, could now distinguish larger structures of manifold conformation; long rows sometimes more closely fitted together all twining and twisting in snake-like motion. But look! What was that? One of the snakes had seized hold of its own tail, and the form whirled mockingly before my eyes. As if by a flash of lightning I awoke; and this time also I spent the rest of the night in working out the consequences of the hypothesis.”
So the snake he saw holding its own tail in its mouth was the the circular structure or closed ring structure of benzene. He immediately woke up and worked out his dream on the paper and by morning he had discovered the chemical structure of benzene.
From the chemical point, the formula of benzene is C6H6. Kekule proposed the following structure to explain the number of substitution compounds which have been synthesized using this structure.
Still there were problems in explaining the two different compounds obtained when hydrogen atoms on adjacent carbons were substituted with two different radicals like Chloride, Nitrate, Iodide or CxHy. This is called ortho disubstituion. That is to say that C6H4XY will form two different ortho isomers depending on whethere substitution has taken place C-C bond or C=C bond. But such isomers have never been found. Kekule tried to explain this by saying that single and double bonds oscillate and thus become identical. Dr. Linus Pauling later on proposed resonance phenomenon, in which there are no purely single and double bonds but something in between and thus all C-C bonds are equivalent.
This has been conformed by UV analysis which shows all C-C bonds of equal strength and indistinguishable. This is like the Hindu God Shiva when He assumed ardhnarishwar or androgynous form to show that both male and female forms coexist in the body. The final outcome depends upon which of these dominate at a given time.
In the end of a lecture explaining the discovery of benzene, he said
Scientists at Oregon State University have developed a blue pigment. Mas Subramanian and his students have this to their credit. The dye is environmentally friendly and nontoxic. It is called YInMn Blue.
This is good news, because many inorganic blues are toxic or cause cancer, such as Prussian blue, cobalt blue, or ultramarine blue.
There is yet another property this dye possesses. It reflects light from sunlight especially in the infrared (heat) part of the spectrum. It is about 40% higher in reflectivity than most blue colors. This could prove to be ideal for paints used on cars, roofs, and other applications where keeping cool is desirable.
This will help in reducing the amount of energy consumption in cooling the vehicles as lesser air conditioning wil be required because it will reflect away much of the heat from the falling light. Because the paint is reflecting much of the energy, it tends to last longer as it is not broken down by the absorbed energy.
The compound was discovered by chance in the laboratory when a student heated a sample of manganese oxide (which is black) to 2,000 degree F. When it came out of the oven, it had been transformed into a bright blue color.
Subsequent analysis showed the compound had a trigonal bipyramidal structure—the shape of two pyramids pointing in opposite directions and joined at a triangular base. The central manganese atom is surrounded by five oxygen atoms. But other compounds—yttrium oxide and indium oxide—are required to stabilize the blue crystals. Another application wil be paint the roof tops with this dye and save much energy.
Darwin, the father of evolution, had postulated that the species evolve constantly to adjust to the changing environment and climatic changes but this change is gradual in nature and takes place over thousands of years. But man is proving him wrong.
Being an expert killer backed by technical advanced equipment, man is bringing rapid changes which are perceptible within much shorter time. Man is super predator and its peculiar hunting preferences are forcing many species particularly of fish and large sized land animals to evolve at a rapid pace than the nature would have done.
There are stories of attacks by sharks on people venturing into sea and of being killed by lions or other carnivorous animals but they fade away when compared to the man. Scientists at the Victoria university at British Columbia in Canada who are studying the changes and the harm being brought upon the fauna by the man has termed the man as “Super Predator“
In general the man hunts the largest of the animals. For examples adults of lions and tigers to flaunt them as the trophies of their valour and skill as opposed to the hunting animals who generally go far the weakest and younger prey.
Thus the man depletes the mature “reproduction capital” instead of the “reproductive interest” of the hunted species. For example, fish is caught in the nets and nets are so constructed as to retain the larger fish and filter out the smaller ones.
This is causing the the fish to mate early and produce the smaller broods. The size is diminishing. This is because the fish is also evolving techniques to survive and producing fish of smaller varieties which can pass through the larger net openings.
Man has hunted the sea creatures 14 times more than the sea predators and 9 times more than the land animals. Man is going for the bigger animals like sharks, tuna fish and marlin. This is changing the ecosystem at a much faster pace than nature.
Over Killing of the land predators has resulted in the increase of herbivore population. This increase is putting pressure on many resources and robbing the food from insects and birds which we cherish. And also resulting in producing the disease prone herbivorous animals.
Coconut grow in the coastal areas. In India, whole of the coast is dotted with coconut trees. Kerala tops the list in coconut plantations. Known as Coconut in English, Narikela in Sanskrit & Nariyal in Hindi, coconuts can grow to between 15 and 30 m tall in plantations. Their trunks are ringed with scars where old leaves have fallen. The top of the trunk is crowned with a rosette of leaves.
Fruits are called coconuts. They are oval and covered with a smooth skin which can be bright green, brilliant orange or ivory coloured. Below the skin is a thick fibrous layer which is used for coir. The next layer is the shell of the seed with the three characteristic ‘eyes’.
The coconut finds so many uses. The shell may be used to make charcoal which is used in the water filters for absorbing the coloring contaminants. The inside of the shell is lined with a white, edible layer called the meat. This is used to make chemicals, and medicinal products. The fluid inside the seed cavity is known as coconut water. This fluid contains many minerals and is taken as such to rejuvenate the body. It is recommended in case of dehydration caused by diarrhea. It has a cooling effect and removes the body heat in summers. When seeds germinate, the new shoot sprouts from one of the eyes. Due to so many uses, in India it has been called the ‘tree of heaven’ or ‘Kalpavriksha‘.
In India, it has great spiritual value. The three ‘eyes’ of the coconut represent the three eyes of the great god Shiva. An earthen pot or pitcher, called a purnakumbha is filled with water and mango leaves and a coconut is placed on top. This purnakumbha is used in the ritual of worship and adoration of the gods, called puja. It is placed as a substitute for the deity or by the side of the deity. The purnakumbha literally means a ‘full pot’ in Sanskrit. It represents Mother Earth, the water the giver of life, the leaves life itself, and the coconut divine consciousness.
In South Asia, coconuts are named Sriphala or fruit of the Gods and symbolize complete usefulness, selfless service, prosperity and generosity. The palms are believed to be the embodiment of the ancient Indian concept of kalpavriksha, or the tree which grants all wishes. It plays an essential role in many religious and social functions in South Asia.
Coconut is an integral ingredient of South Indian cuisine. It is used in one form or another in the food. It is used to make chutneys, thickened with milk and sugar to make delicious sweets. It is milk is used in many fish preparations. Its oil is used for cooking and hair dressing.
