After Aryabhatiya was translated into Arabic c. Aryabhata discussed the concept of sine in his work by the name of ardha-jyawhich literally means "half-chord". For simplicity, people started calling it jya. When Arabic writers translated his works from Sanskrit into Arabic, they referred it as jiba. However, in Arabic writings, vowels are omitted, and it was abbreviated as jb.

Later writers substituted it with jaibmeaning "pocket" or "fold in a garment ". In Arabic, jiba is a meaningless word. Later in the 12th century, when Gherardo of Cremona translated these writings from Arabic into Latin, he replaced the Arabic jaib with its Latin counterpart, sinuswhich means "cove" or "bay"; thence comes the English word sine.

This problem was also studied in ancient Chinese mathematics, and its solution is usually referred to as the Chinese remainder theorem. It turns out that the smallest value for N is In general, diophantine equations, such as this, can be notoriously difficult. In AryabhatiyaAryabhata provided elegant results for the summation of series of squares and cubes: [ 27 ].

Aryabhata's system of astronomy was called the audAyaka systemin which days are reckoned from udaydawn at lanka or "equator". Some of his later writings on astronomy, which apparently proposed a second model or ardha-rAtrikAmidnight are lost but can be partly reconstructed from the discussion in Brahmagupta 's Khandakhadyaka. In some texts, he seems to ascribe the apparent motions of the heavens to the Earth's rotation.

He may have believed that the planet's orbits are elliptical rather than circular. Aryabhata correctly insisted that the Earth rotates about its axis daily, and that the apparent movement of the stars is a relative motion caused by the rotation of the Earth, contrary to the then-prevailing view, that the sky rotated. In the same way that someone in a boat going forward sees an unmoving [object] going backward, so [someone] on the equator sees the unmoving stars going uniformly westward.

The cause of rising and setting [is that] the sphere of the stars together with the planets [apparently? Aryabhata described a geocentric model of the Solar System, in which the Sun and Moon are each carried by epicycles. They in turn revolve around the Earth. The positions and periods of the planets was calculated relative to uniformly moving points.

In the case of Mercury and Venus, they move around the Earth at the same mean speed as the Sun. In the case of Mars, Jupiter, and Saturn, they move around the Earth at specific speeds, representing each planet's motion through the zodiac. Most historians of astronomy consider that this two-epicycle model reflects elements of pre-Ptolemaic Greek astronomy.

Solar and lunar eclipses were scientifically explained by Aryabhata. He states that the Moon and planets shine by reflected sunlight. Instead of the prevailing cosmogony in which eclipses were caused by Rahu and Ketu identified as the pseudo-planetary lunar nodeshe explains eclipses in terms of shadows cast by and falling on Earth. Thus, the lunar eclipse occurs when the Moon enters into the Earth's shadow verse gola.

He discusses at length the size and extent of the Earth's shadow verses gola. Later Indian astronomers improved on the calculations, but Aryabhata's methods provided the core. His computational paradigm was so accurate that 18th-century scientist Guillaume Le Gentilduring a visit to Pondicherry, India, found the Indian computations of the duration of the lunar eclipse of 30 August to be short by 41 seconds, whereas his charts by Tobias Mayer, were long by 68 seconds.

Considered in modern English units of time, Aryabhata calculated the sidereal rotation the rotation of the earth referencing the fixed stars as 23 hours, 56 minutes, and 4. Similarly, his value for the length of the sidereal year at days, 6 hours, 12 minutes, and 30 seconds As mentioned, Aryabhata advocated an astronomical model in which the Earth turns on its own axis.

Thus, it has been suggested that Aryabhata's calculations were based on an underlying heliocentric model, in which the planets orbit the Sun, [ 38 ] [ 39 ] [ 40 ] though this has been rebutted. Aryabhata's work was of great influence in the Indian astronomical tradition and influenced several neighbouring cultures through translations.

The Arabic translation during the Islamic Golden Age c. Some of his results are cited by Al-Khwarizmi and in the 10th century Al-Biruni stated that Aryabhata's followers believed that the Earth rotated on its axis. His definitions of sine jyacosine kojyaversine utkrama-jyaand inverse sine otkram jya influenced the birth of trigonometry. In fact, the modern terms "sine" and "cosine" are mistranscriptions of the words jya and kojya as introduced by Aryabhata.

As mentioned, they were translated as jiba and kojiba in Arabic and then misunderstood by Gerard of Cremona while translating an Arabic geometry text to Latin. He assumed that jiba was the Arabic word jaibwhich means "fold in a garment", L. Aryabhata's astronomical calculation methods were also very influential. Along with the trigonometric tables, they came to be widely used in the Islamic world and used to compute many Arabic astronomical tables zijes.

In particular, the astronomical tables in the work of the Arabic Spain scientist Al-Zarqali 11th century were translated into Latin as the Tables of Toledo 12th century and remained the most accurate ephemeris used in Europe for centuries. Calendric calculations devised by Aryabhata and his followers have been in continuous use in India for the practical purposes of fixing the Panchangam the Hindu calendar.

In the Islamic world, they formed the basis of the Jalali calendar introduced in CE by a group of astronomers including Omar Khayyam[ 46 ] versions of which modified in are the national calendars in use in Iran and Afghanistan today. The dates of the Jalali calendar are based on actual solar transit, as in Aryabhata and earlier Siddhanta calendars.

This type of calendar requires an ephemeris for calculating dates. Although dates were difficult to compute, seasonal errors were less in the Jalali calendar than in the Gregorian calendar. Aryabhatta Knowledge University AKUPatna has been established by Government of Bihar for the development and management of educational infrastructure related to technical, medical, management and allied professional education in his honour.

The university is governed by Bihar State University Act The reason for his death is not aryabhatta zero history gibson but he died in 55o CE. Bhaskara I, who wrote a commentary on the Aryabhatiya about years later wrote of Aryabhata Aryabhata is the master who, after reaching the furthest shores and plumbing the inmost depths of the sea of ultimate knowledge of mathematics, kinematics and spherics, handed over the three sciences to the learned world.

Add four tomultiply by eight, and then add By this rule the circumference of a circle with a diameter of can be approached. In this system, he gave values to 1, 2, 3,…. To denote the aryabhatta zero history gibson numbers likehe used these consonants followed by a vowel. French mathematician Georges Ifrah claimed that numeral system and place value system were also known to Aryabhata and to prove her claim she wrote.

It is extremely likely that Aryabhata knew the sign for zero and the numerals of the place value system. It is believed that Zero was used for the first time as a decimal digit, in a mathematical text known as the Lokabhivaga. This was by none other than the famed astronomer Brahmagupta. Cool Fact: It took a while for the idea of the number Zero to reach Europe — as late as the 12 th century A.

Cool Fact: Fibonacci actually made use of the Hindu-Arabic numeral system in his book. This system sees him give values to numbers 1,2,3. Needless to say, back in the day Aryabhata wrote his work in the ancient language of Sanskrit. That being said, it is widely known that the Sanskrit language wielded an enormous influence on the way the English numerical system was written.

If there is an attempt made to divide any number by the number zero, what is it we get? Bonus Fact: This dilemma forms the root basis of several advanced mathematical topics, such as Calculus. His work has also been cited in the context of philosophy and education. The holistic approach he adopted, blending mathematics with astronomy and philosophical thought, encourages a view of knowledge as interconnected rather than compartmentalized.

An anecdote that highlights Aryabhata's methodical approach involves his response to the question of lunar eclipses.

This explanation underscored his reliance on observation and reasoning, principles that later became cornerstones of scientific inquiry. Aryabhata's legacy is not merely a matter of historical interest; it prompts us to reflect on the nature of knowledge and its evolution. As we consider the impact of his work on contemporary mathematics and science, we might ask: How can the principles of inquiry and interconnectedness that guided Aryabhata inspire current scientific practices?

The story of Aryabhata is a testament to the power of ideas and the enduring influence of ancient knowledge on modern thought. His contributions remind us that the pursuit of knowledge is a continuous journey, one that transcends time and cultural boundaries, inviting us all to explore the depths of understanding that science offers.
