What were the strengths and weaknesses of Cleopatra?

User Avatar

Asked by Wiki User

Cleopatra's strength was that she was ruler of Egypt and the god(known from citizens of Egypt). She had the power to control what came in and out of Egypt. She had also controlled what went on in Egypt. Cleopatra's weaknesses is that she went with many men, but never ended up with one. She was weak as to power with Gaius Julius Caesar and never completed the goal. She was also weak in the way that she was not able to rule as her mother has expected. "She captivated the two greatest Romans of her day, and because of the third she destroyed herself."

Would it be better if man's dream of flying had never come true?

User Avatar

Asked by Wiki User

No. It has opened up the world and made it a smaller place. It has made it easier for people to see new places and educate themselves about the world. It has meant that people who have emigrated to other countries have a better chance of being able to get back to where they came from for visits. One time, once someone left a country, they never had the chance to see their home and family again. Along with travel, there are other practical advantages, like being able to get a patient to a hospital very quickly in a helicopter or a plane.

When was science discovered?

User Avatar

Asked by Wiki User

Science (the investigation of how the physical world functions) began with the earliest civilizations, many of whom initially ascribed much of natural phenomena to gods. Science may have started when people began asking such questions as why is the sky blue during the day and where does life come from.

Another answer:

Science wasn't discovered. It is a way of thinking and of looking at the world. It gradually evolved as people discovered what worked and what didn't. People have always asked themselves questions about the world around them and tried to give answers. Science relies on the fact that we test our ideas by experiment, and are prepared to discard those which do not fit the experimental results. Elements of the scientific method emerged in ancient times, but its full evolution followed the Renaissance.

What is a pathology department?

User Avatar

Asked by Wiki User

A pathology department is similar to a medical detective squad. It is a section of a hospital or medical institute where pathologists research and analyze various aspects of diseases. These professionals study tissues, blood, and other samples to figure out what's going on within your body. Consider them medical investigators who utilize microscopes and other modern instruments to uncover information about ailments.

Pathologists assist doctors in making accurate diagnosis and determining the best course of treatment for patients. They are critical in understanding the nature of diseases, which is required for proper medical management. So, in the realm of healthcare, the pathology department is a behind-the-scenes hero, trying to solve health puzzles and secure the best possible outcomes for patients.

Students who want to learn more about pathology and different concepts of pathology, I would suggest them an online video-lecture course – Pathology for Undergrads on DigiNerve.

The course consists of high-quality and informative video lectures and notes which makes it so easy for the students to grasp the topics. Each topic has relevant case discussions to boost students' learning and give them with a clinical orientation. A large number of histological and gross images, as well as specimens, have been included to help pupils correlate.

Apart from the just teaching, the course also takes care of what a student has really understood, through its self-assessment questions. Through these series of questions, students can find their pain areas in the subject, work more on them and eventually ace the topic and master the subject.

What is the bowie knife made from?

User Avatar

Asked by Wiki User

Bowie knives can be made from various types of steel, and the choice of steel often depends on factors such as the intended use of the knife, the preferences of the maker, and the desired performance characteristics. Here are some common materials used in the construction of Bowie knives:

High Carbon Stainless Steel:

Bowie knives made from high carbon stainless steel offer a balance between corrosion resistance and edge retention. Popular stainless steels for Bowie knives include VG-10 and others.

Carbon Steel:

Carbon steel Bowie knives are known for their toughness and ease of sharpening. Steels like 1095 are commonly used and favored for their durability.

Damascus Steel:

Some Bowie knives feature blades made from Damascus steel, a type of steel with a distinctive layered pattern created through the folding and forging of different steel alloys. While Damascus steel can be visually striking, the specific performance characteristics depend on the types of steel used in its construction.

Tool Steel:

Bowie knives made from tool steels, such as 1095 or O1 tool steel, are chosen for their toughness and resistance to wear. These steels are suitable for heavy-duty use.

Powdered Metallurgy Steel:

Some high-end Bowie knives utilize powdered metallurgy (PM) steel, such as CPM S30V or CPM 154. PM steel is known for its fine grain structure, which can enhance edge retention and overall performance.

Stainless Steel Alloys:

Various stainless steel alloys, including AUS-8 and 440C, are used in Bowie knife construction. These alloys offer corrosion resistance and ease of maintenance.

High-End Stainless Steels:

Premium stainless steels like CPM S30V, CPM S35VN, and others are employed in high-quality Bowie knives. These steels provide excellent edge retention, corrosion resistance, and overall performance.

Carbon Damascus Steel:

In addition to stainless Damascus, some Bowie knives feature carbon Damascus steel. Carbon Damascus can offer a unique aesthetic and may be preferred by those who appreciate the characteristics of carbon steel.

It's important to note that the choice of steel is just one aspect of Bowie knife construction. The heat treatment and manufacturing processes also play a significant role in determining the knife's overall performance. Additionally, the handle material, blade geometry, and overall design contribute to the knife's functionality and appearance. The preferences of the knife maker and the intended use of the Bowie knife often guide the selection of materials.

How was mendeleyev able to predict the existence of elements that had not yet discovered?

User Avatar

Asked by Wiki User

Because there were gaps in the periodic table, which he invented. Unlike other scientist of the time who tried to make the elements fit theircategorising system, such as Newlands and his law of octaves, Mendeleev came to the conclusion that they had not discovered all the elements as he noticed patterns that allowed you to categorise elements if you left gaps that undiscovered elements could fill.

Why was John Dalton's science and discoveries that he did so important?

User Avatar

Asked by Wiki User

John Dalton's science and discoveries were important because they laid the foundation for modern atomic theory. His work on the properties of gases led him to propose that all matter is made up of tiny, indivisible particles called atoms. He also introduced the concept of atomic masses and ratios in chemical reactions. Dalton's theories revolutionized the understanding of the composition and behavior of matter, providing a framework for further scientific inquiry and discovery.

What is a chief function of carbonic acid in the body?

When was the periodic table created and who by?

User Avatar

Asked by Wiki User

The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
