Have you ever known the bird stricken by thunder? It rarely happen, only in a small possibility. It is same with aircraft.

Everyday the earth is stricken with 40.000 lightnings. Because of the wide of earth surface, the possibility of aircraft hit by lightning is very small. The rate, every year there is an aircraft hit by lightning. Furthermore, the bird has smaller possibility. Especially, the birds rarely fly in rain and lightning.

Lightning arrester in aircraft is not the real lightning arrester. This tool called static discharger that has function to release static electrical current. When the aircraft body is struck by lightning, the electrical current in the body will flow to static discharger that formed as sharp tip (physic: the electrical

Have ever though about cosmos edge? Some one else do. I have read about this in a science book. A reader is asked about cosmos edge and a scientist has answered it.

The thousand years ago, a big explosion called Big Bang, planets, stars and galaxies are begin to formed. The cosmos is outgrown. The matters in it move away from each other. You can go imagine the matters in a ball surface that swells by time. So take an instance, an ant that moves in ball surface will be back to the first place. It has no edge like the cosmos.

Moon is the nearest satellite with earth. However, it is impossible for human to life in moon. It is far different with our earth. 

Moon has the extremely different temperature within daylight and night. When daylight (we see the full moon), the temperature can be more than 100oC. The water will boil in this temperature. In the night (we can see dead moon from earth), the temperature can reach -147oC, very cold. Read the rest of this entry »

Don’t you know that lithium can be burn? Lithium is used as laptop battery. Of course the producers have evaluated lithium security. Don’t try to open the battery because it can be burn if exposed with humidity.

Pour the burn lithium with water will make the fire grows. Instead you can use the chemical extinguisher. The hot cells also can make its cover become hot that finally produces fire. So, don’t ever leave the battery in hot temperature place like under the sun or in car that parked in daylight. Read the rest of this entry »

The book Meteorology Today by Ahrens, C. Donald says that a cloud becomes electrified as hail falls trough a region in the cloud of super cooled droplets and ice crystals. As liquid droplets collide with a hailstone, they freeze on contact and release latent heat. This will keep the surface of the hailstone warmer than that of the surrounding ice crystals. When the hailstone comes in contact with an ice crystal, an important phenomenon occurs: electrons flow from the colder object toward the warmer object. So, the hailstone becomes negatively charged.

The same effect occurs when super cooled droplets come in contact with a hailstone and tiny splinters of positively charged ice break off. These lighter positively charged particles are then carried to the upper part of the cloud by updrafts. The hail left with a negative charge, falls towards the bottom of the cloud, thus the lower part of the cloud becomes negatively charged. These negatives charges are then discharged as lightning.

Black hole can be found in our galaxy. There are many black holes spread within the galaxy. What is black hole and how does it happen?

The materials in a star have gravity. Gravity is tensile strength within 2 materials. The gravity that occurs within the star materials make it becomes more solid. Besides, there is burning a burning process in the star. The burning energy will restrain the star so itdoesn’t become small.

When hydrogen (fuel) is end, nothing can restrain the gravity. In this condition, the star become small and solid. When it has become so solid (with some kilometers of radius), all matters include light will be pulled inside. That is why this star is called hole. All lights is pulled in the star, nothing come out from it. Someone outside the star will not see a light at all from the star. So this star is called black hole.

An unique artistic room interior in this hotel was found is Los Angeles. You can check out through these pictures. The hotel is cheap enough. It is belong to Figuroa family. It represents the old building, clenched within shops, offices and bar row in LA downtown.

You can see further the unique design of this hotel room interior through foundus.cn. The building itself is established at the beginning of 19th century.

Apakah anda sudah mengetahui bahwa keanekaragaman hayati dunia terus berkurang. Penyebabnya ialah adanya perubahan iklim dan kegiatan manusia misalnya polusi, pembakaran hutan, penangkapan ikan, pemeliharaan binatang liar serta perburuan. Hal tersebut berdampak nyata pada hilangnya 35% lahan bakau dan 20% terumbu karang di dunia.

Ekosistem alam yang diubah menjadi gedung, pemukiman, lahan pertanian membuat habitat alami makin berkurang, demikian species tidak mendapat tempat hidup dan mati perlahan. Punahnya species dalam 100 th terakhir telah dipercepat oleh manusia menjadi 100 xlipat. Perubahan iklim global yang mempengaruhi perubahan penyebaran species, besaran populasi, waktu reproduksi, migrasi dan sebagainya turut memperparah keadaan.

Beberapa species seperti beruang kutub kehilangan habitatnya dan sebagian tak mampu mencapai lokasi tujuan yang beriklim sesuai saat migrasi, kasihan sekali… . Hal ini memerlukan percepatan pengubahan teknologi yang tidak menghasilkan gas rumah kaca dan tanpa karbon. Semua itu bisa menyelamatkan 15-20% species dari kepunahan.

Have you ever got weight loss fastly ? The fact is fastly weight loss usually isn’t durable. Because after you get weight loss, you can have more bigger desire to eat certain food.
