05–06 July - The Battle of Wagram in 1809

The Battle of Wagram (5–6 July 1809) was a military engagement of the Napoleonic Wars that ended in a costly but decisive victory for Emperor Napoleon I's French and allied army against the Austrian army under the command of Archduke Charles of Austria-Teschen. The battle led to the breakup of the Fifth Coalition, the Austrian and British-led alliance against France.

In 1809, the French military presence in Germany was diminished as Napoleon transferred a number of soldiers to fight in the Peninsular War. As a result, the Austrian Empire saw its chance to recover some of its former sphere of influence and invaded the Kingdom of Bavaria, a French ally. Recovering from his initial surprise, Napoleon beat the Austrian forces and occupied Vienna at the beginning of May 1809. Despite the string of sharp defeats and the loss of the empire's capital, Archduke Charles salvaged an army, with which he retreated north of the Danube. This allowed the Austrians to continue the war. Towards the end of May, Napoleon resumed the offensive, suffering a surprise defeat at the Battle of Aspern-Essling.

05–07 July - The naval Battle of Chesme in 1770

The naval Battle of Chesme took place on 5–7 July 1770 during the Russo-Turkish War (1768–1774) near and in Çeşme (Chesme or Chesma) Bay, in the area between the western tip of Anatolia and the island of Chios, which was the site of a number of past naval battles between the Ottoman Empire and the Republic of Venice. It was a part of the Orlov Revolt of 1770, a precursor to the later Greek War of Independence (1821–29), and the first of a number of disastrous fleet battles for the Ottomans against Russia.

'It is an incomparable journey where the Guru leads you from the visible to the invisible, from the material to the divine, from the ephemeral to the eternal. Happy Guru Purnima!! "

Guru Purnima (Poornima) is also known as Vyasa Purnima marks the birthday of Ved Vyasa.It is a tradition dedicated to spiritual and academic Gurus, who are evolved or enlightened humans, ready to share their wisdom with very little or no monetary expectation, based on Karma Yoga. It is celebrated as a festival in India, Nepal and Bhutan by the Hindus, Jains and Buddhists. This festival is traditionally observed by Hindus, Buddhists and Jains to revere their chosen spiritual teachers / leaders and express their gratitude.

The festival was revived by Mahatma Gandhi to pay tribute to his spiritual guru Shrimad Rajchandra.

05 July - Philosophiæ Naturalis Principia Mathematica published in 1687.

Philosophiæ Naturalis Principia Mathematica (Latin for Mathematical Principles of Natural Philosophy),often referred to as simply the Principia, is a work in three books by Isaac Newton, in Latin, first published 5 July 1687.After annotating and correcting his personal copy of the first edition,Newton published two further editions, in 1713 and 1726.The Principia states Newton's laws of motion, forming the foundation of classical mechanics; Newton's law of universal gravitation; and a derivation of Kepler's laws of planetary motion (which Kepler first obtained empirically).

The Principia is considered one of the most important works in the history of science.The French mathematical physicist Alexis Clairaut assessed it in 1747: "The famous book of Mathematical Principles of Natural Philosophy marked the epoch of a great revolution in physics. The method followed by its illustrious author Sir Newton ... spread the light of mathematics on a science which up to then had remained in the darkness of conjectures and hypotheses."

A more recent assessment has been that while acceptance of Newton's theories was not immediate, by the end of the century after publication in 1687, "no one could deny that" (out of the Principia) "a science had emerged that, at least in certain respects, so far exceeded anything that had ever gone before that it stood alone as the ultimate exemplar of science generally".

In formulating his physical theories, Newton developed and used mathematical methods now included in the field of calculus. But the language of calculus as we know it was largely absent from the Principia; Newton gave many of his proofs in a geometric form of infinitesimal calculus, based on limits of ratios of vanishing small geometric quantities.In a revised conclusion to the Principia (see General Scholium), Newton used his expression that became famous, Hypotheses non fingo ("I feign no hypotheses").

03 July - Saint Thomas martyred in AD 72

St. Thomas was one of Jesus' disciples. He is perhaps best known for being the one disciple who wanted proof of Jesus' resurrection. St. Thomas is celebrated with a feast day in both the Roman Catholic and Orthodox churches. He is often referred to as Doubting Thomas, and also the name The Twin.

Many Christians see themselves in St. Thomas because he doubted the resurrection until he received proof from Christ himself. He also confessed to not understanding Jesus when Christ told his disciples at the Last Supper that he was preparing a place for them.

According to Syrian Christian tradition, Saint Thomas was allegedly martyred at St.Thomas Mount in Chennai on 3 July in AD 72, and his body was interred in Mylapore.Ephrem the Syrian states that the Apostle was killed in India, and that his relics were taken then to Edessa. This is the earliest known record of his death.

The records of Barbosa from early 16th century witness that the tomb was then maintained by a Muslim who kept a lamp burning there.The San Thome Basilica Mylapore, Chennai, Tamil Nadu, India presently located at the tomb was first built in the 16th century by the Portuguese and rebuilt in the 19th century.St. Thomas Mount has been a revered site by Hindus, Muslims, and Christians since at least the 16th century.
