Since earliest known civilization, Sumerian, more than six thousand years ago, a small group of elites is enslaving masses in the name of religion and gods, under the disguise of so-called law. Over it has changed names, terminologies, packaging, wrapping, branding, and forms, but basically it remains the same, always, the Oligarchy i.e., few bossing around everyone else. What happens is that this artificial system of enslavement originally designed by so-called gods fall to the war and welfare after a while, people revolt and the gods or masters just re-wrap, rename and re-brand the same old, tell masses that it is fixed now and will work now. It is thrown back to the masses with new false hopes and wishes. People accept it just to yield the same results and same old disappointment. Whether these were Sumerian gods, Babylonian demi-gods, Egyptian pharaohs, Greek, Roman and other kings and emperors, or modern dictators, president or prime ministers, the story is the same every single time. People fall prey to the new promises of hope and a better life and get trapped again in the same instrument of slavery, catching them in a new shape and form. Hence, each an opportunity to attain freedom and prosperity is missed during false hopes and deceptive promises. Problem is that masses are waiting for a true god or master to rescue them from this misery since forever. Fortunately, gods and masters are not the answer. The path to true freedom and prosperity is that the people realizing their own power potential, break down these ages old chains and everyone taking full control of his and her own life. Only if you can rescue you can free yourself from this eternal prison. It starts with arming yourself with knowledge, reason, and logic. Freedom begins with the freedom of your mind. Stop relying on he said, she said, they said. Find it yourself. Learn logic. Logically analyze every claim and claim of knowledge presented to you as truth. Study history. And do not repeat mistakes. Understand that they are making us do the same again and again and expect different results. Einstein said that this is the true definition of insanity. Give up the insanity. Act like a sane, grown-up adult. Get rid of gods and masters. Nature has given you a hidden hand that automatically provides you with amazing results. In the last two to three hundred years, this hidden hand has generated incredible wealth and prosperity that was completely unimaginable just two to three hundred years ago anywhere in the world. From abject poverty and feudalism, the world has come to a point where its poverty and violence are declining, and standards of living are skyrocketing. We are flying in space, sailing at the bottoms of oceans, communicating with the other end of the world instantaneously, producing and preserving food in massive quantities, have incredible protections from extreme temperatures and weathers, and ability to make love even at old age. We doubled life expectancy in the last century. The only thing we need to do now is to end the insanity of doing the same and expecting different results. We must take back the power from our masters, trust the power instantaneous, natural order in free markets and take our destiny in our own hands. Read Anatomy of the state by Murray Rothbard and decide yourself if you want masters to do it for you or is it better for you to take back the control.

This scientific observation practicum aims to gain experience in recording and explaining experimental obsevation, develop skills in handling tools and moving solid and liquid materials, familiarize yourself with the work safety procedures in the laboratory. For college students, it is very interesting to do scientific observation experiments, because can find out which parts experienced a decrease in freezing faster. The decrease in freezing is the difference between the freezing point of the solvent and the freezing point of the solution, where the freezing point of the solution is lower than the freezing point of the solvent. Testing of colligative properties of freezing point reduction can be done using ingredients namely, salt (NaCl), sugar (glucose), wheat flour, and ice cubes. Praktikum pengamatan ilmiah ini bertutujuan untuk memperoleh pengalaman dalam mencatat dan menjelaskan pengamatan percobaan, mengembangkan keterampilan dalam menangani alat dan memindahkan bahan padat maupun cairan, membiasakan diri dengan tata cara keselamatan kerja di laboratorium. Bagi mahasiswa, sangat menarik melakukan eksperimen pengamatan ilmiah, karena dapat mengetahui bagian mana yang mengalami penurunan titik beku lebih cepat. Penurunan titik beku adalah selisih antara titik beku pelarut dan titik beku larutan, dimana titik beku larutan lebih rendah di banding titik beku pelarut. Pengujian sifat koligatif penurunan titik beku dapat dilakukan dengan menggunakan bahan yaitu, garam (NaCl), gula (Glukosa), tepung terigu, dan es batu.

The esterification of carboxylic acids (CA) with alcohols has a great importance for the chemical industry [1-2]. Recent studies reveal that the esters of CA mat be used as plasticizers, solvents, and components of biofuel (BF). Particularly, the esters of butanoic acid (BA) with n-butanol or n-heptanol have a potential as the BF components. Promissing results have been obtained for the esters of BA added to canola biodiesel in varying concentrations by measuring the cloud point using Tanaka mini pour/cloud point tester MPC-102L according to ASTM method D2500 [3]. However, a little is known about esterification of monocarboxylic acids (MCA) with ketoalcohols (hydroxyacetone, 1-hydroxybutan-2-one or 1-hydroxypentan-2-one).

Titik beku adalah suhu dimana tekanan uap cairan sama dengan tekanan uap padatannya. Titik beku larutan lebih rendah daripada titik beku pelarut murni. Hal ini disebabkan zat pelarutnya harus membeku terlebih dahulu, baru zat terlarutnya. Jadi larutan akan membeku lebih lama daripada pelarut. Setiap larutan memiliki titik beku yang berbeda. Titik beku suatu cairan akan berubah jika tekanan uap berubah, biasanya diakibatkan oleh masuknya suatu zat terlarut atau dengan kata lain, jika cairan tersebut tidak murni, maka titik bekunya berubah (nilai titik beku akan berkurang). Seperti yang kita tahu bahwa titik beku pelarut murni berada pada suhu 0°C, tapi dengan adanya zat terlarut misalnya saja kita tambahkan gula ke dalam air tersebut maka titik beku larutan ini tidak akan sama dengan 0°C lagi, melainkan akan turun menjadi dibawah 0°C, dan inilah yang dimaksud sebagai " penurunan titik beku ". Dalam percobaan ini akan diteliti tentang perubahan titik beku pelarut murni yang telah ditambahkan zat terlarut lain kedalamnya dan mencoba pembuktian bahwa titik beku larutanya akan lebih rendah dibandingkan pelarut murninya. B. Tujuan Penelitian • Menentukan titik beku larutan Urea 1M dan CaCl 2 0,1M • Mengetahui pengaruh adanya zat terlarut terhadap titik beku larutan C. Manfaat Penelitian

Saat ini hampir 10 juta zat kimia telah dikenal manusia, dan hampir 100.000 zat kimia telah digunakan secara komersial. Kebanyakan sisa zat kimia tersebut dibuang ke badan air atau air tanah. Sebagai contoh adalah pestisida yang biasa digunakan di pertanian, industri atau rumah tangga, detergen yang biasa digunakan di rumah tangga atau PCBs yang biasa digunakan pada alat-alat elektronik.

I chose this experiment to see if the type of oil depends on how much heat energy it produces. I wanted to see if a close of enough amount of heat energy in the motor oil that powers our car; we might be able to power our cars with grape seed, coconut oil, or vegetable oil, and a string with nothing on it. So, I found out the heat energy for all of the oils, you will see my findings in my conclusion.

The determination of thermodynamic stability constant suggests that the inclusion complex has appreciable stability and its formation is thermodynamically allowed.The study of the antibacterial activity of the compound and its inclusion complex suggests that inclusion formation increases antibacterial activity significantly.

In the experimental procedure we will measure the heat of neutralization when an acid and base react to form 1 mole of water. This quantity of heat is measured experimentally by allowing the reaction to take place in a thermally insulated Styrofoam cup calorimeter. The heat liberated in the neutralization reaction will cause an increase in the temperature of the solution and of the calorimeter.

The pi-bond between the carbons is very electron rich, and so repels the electrons in a neighbouring bromine molecule inducing a dipole. The electron pair in the pi-bond are attracted to the slightly positive bromines atom causing the double bond to break and the electron pair to become shared by the carbon and the bromine (i.e. forming a new covalent bond. The Br-Br bond breaks by heterolytic fission, forming a Brion. A carbocation is also formed.
