Egypt (i/ˈiːdʒɪpt/; Arabic: مِصر‎ Miṣr, Egyptian Arabic: مَصر Maṣr, Coptic: Ⲭⲏⲙⲓ Khemi), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia, via a land bridge formed by the Sinai Peninsula. It is the world's only contiguous Eurafrasian nation. Most of Egypt's territory of 1,010,408 square kilometres (390,000 sq mi) lies within the Nile Valley. Egypt is a Mediterranean country. It is bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south and Libya to the west.
What country borders Egypt to the south?

Russia, as a member of the Holy Alliance, had operated as the "police of Europe", maintaining the balance of power that had been established in the Treaty of Vienna in 1815. Russia had assisted Austria's efforts in suppressing the Hungarian Revolution of 1848, and expected gratitude; it wanted a free hand in settling its problems with the Ottoman Empire — the "sick man of Europe". The United Kingdom could not tolerate Russian dominance of Ottoman affairs, as that would challenge the British domination of the eastern Mediterranean.
Who did Russia help during the Hungarian Revolution?
****
The answer: Austria

One of the first quantum effects to be explicitly noticed (but not understood at the time) was a Maxwell observation involving hydrogen, half a century before full quantum mechanical theory arrived. Maxwell observed that the specific heat capacity of H2 unaccountably departs from that of a diatomic gas below room temperature and begins to increasingly resemble that of a monatomic gas at cryogenic temperatures. According to quantum theory, this behavior arises from the spacing of the (quantized) rotational energy levels, which are particularly wide-spaced in H2 because of its low mass. These widely spaced levels inhibit equal partition of heat energy into rotational motion in hydrogen at low temperatures. Diatomic gases composed of heavier atoms do not have such widely spaced levels and do not exhibit the same effect.
Who observed the specific heat capacity of H2?
****
The answer: Maxwell


The problem: Answer a question about this article:
In 27 BC, Lusitania gained the status of Roman province. Later, a northern province of Lusitania was formed, known as Gallaecia, with capital in Bracara Augusta, today's Braga. There are still many ruins of castros (hill forts) all over modern Portugal and remains of Castro culture. Numerous Roman sites are scattered around present-day Portugal, some urban remains are quite large, like Conímbriga and Mirobriga. The former, beyond being one of the largest Roman settlements in Portugal, is also classified as a National Monument. Conímbriga lies 16 km from Coimbra which by its turn was the ancient Aeminium). The site also has a museum that displays objects found by archaeologists during their excavations.
What are two large Roman sites that still exist today in Portugal?
****
The answer:
Conímbriga and Mirobriga
