বিভিন্ন জমিদার বাড়ির প্রতি প্রবল আগ্রহ থাকার কারনে মহেড়া জমিদার বাড়িটি একটি বিশেষ স্থান দখল করে নেয় আমাদের মনে। এক দিকে এর স্থাপত্যশৈলী আর অন্যপাশে এর রয়েছে করুন একটি ইতিহাস। এই দুইয়ে মিলে মনের মধ্যে একটি বিশেষ স্থান পায় আমাদের মনে।
১৮৯০ শতকের দিকে কালিচরন সাহা এবং আনন্দ সাহা নামের ২ভাই কলকাতায় ডাল ও লবণ ব্যাবসা করে প্রচুর টাকা আয় করে চলে আসেন মহেড়া গ্রামে। এই গ্রামে তারা সুবিশাল জমির উপর তৈরি করেন এই বিশাল বাড়িটি। তখন তারা গ্রামবাসীদের উপর টাকা দাদন খাটাতেন এবং জনগনের জীবন যাত্রার উন্নতি ঘটান। তাহলে তারা কি তখন জমিদার ছিলেন? না তখনও জমিদার প্রথা চালু ছিল না।তাই ব্রিটিশরা যখন জমিদার প্রথা চালু করেন তখন কালীচরণ সাহা ও আনন্দ সাহার ছেলেরা করটিয়ার ২৪ পরগনার জমিদারদের কাছে থেকে একটি অংশ বিপুল অর্থের বিনিময়ে কিনে নেয় এবং এখান থেকে শুরু হয় জমিদারীর উত্থান। এই জমিদারেরা তখন এলাকার স্কুল,রাস্তাঘাত,পানির ব্যাবস্থা সহ বিভিন্ন জনকল্যানমূলক কাজ করে জনগনের মনে ভালবাসা এবং সম্মানের স্থান লাভ করেন।
এই বাড়িটিতে রয়েছে ৩টি সুবিশাল অট্টালিকা এবং কাছারি ঘর যেগুলো মহারাজা লজ, আনন্দ লজ, চৌধুরী লজ এবং কালীচরণ লজ নামে পরিচিত। এছাড়াও রয়েছে মেহমান খানা, আত্মীয় স্বজন কর্মচারীদের জন্য থাকার বাড়ি, পুকুর,মন্দির, ফুলের বাগান আরও অনেক কিছু যার সৌন্দর্যে আপনি অবাক হতে বাধ্য।
এই বাড়িটির রয়েছে একটি কলঙ্কিত ইতিহাস যার কারনে এই জমিদারদের এই দেশ থেকে চলে যেতে হয়। এক রকম মনে প্রচণ্ড দুঃখ নিয়ে তারা এই দেশ ছেড়ে চলে যান যা আমাদের এই ভিডিও তে বিস্তারিত বলা রয়েছে।
কিছু প্রয়োজনীয় তথ্য দেওয়া দরকার।
১। কিভাবে যাবেনঃ ঢাকার মহাখালী থেকে নিরালা বাস পাবেন যার টিকিট এর মুল্য ১৬০ টাকা। এই ছাড়াও আরও কিছু বাস পাবেন যেগুলা লোকাল। সেগুলোতে বাস ভাড়া একটু কমে পাবেন।বাস নিয়ে দুবাইল নেমে জান।সেখানে সিএনজি পাবেন ৭৫ টাকাতে চলে যান জমিদার বাড়িতে।
২। প্রবেশ মুল্যঃ বাড়িতে প্রবেশ এর টিকিট এর মুল্য ৫০ টাকা করে। আর পাস্রা পুকুর এ প্রবেশ করতে লাগবে ২০ টাকা।
৩। কি খাবেনঃ ভাত, দাল,মুরগি এর প্যাকেজ ৮০ টাকা যেখানে ভাত এবং ডাল আপনার জন্য আনলিমিটেড। আপনি যখন খেতে বসবেন আপনাকে এমন ভাবে খাওয়ানো হবে যাতে আপনার মনে হবে আপনি নিজের বাসায় খাচ্ছেন। এরকম আতিথেয়তা খুব কমই পাওয়া যায়। আর আপনার একটু খানি আন্তরিকতা আপনার ভ্রমনকে করে তুলবে আরও উপভোগ্য।
আমরা আমাদের পুরো ভ্রমনটি একটি ভিডিও দারা উপস্থাপন করার চেষ্টা করেছি। আশা করি আপনাদের ভাল লাগবে।

Enormous volcanoes vomited lava over the ancient Earth much more often than geologists had suspected. Eruptions as big as the biggest previously known ones happened at least 10 times in the past 3 billion years, an analysis of the geological record shows.

Such eruptions are linked with some of the most profound changes in Earth’s history. These include the biggest mass extinction, which happened 252 million years ago when volcanoes blanketed Siberia with molten rock and poisonous gases.

“As we go back in time, we’re discovering events that are every bit as big,” says Richard Ernst, a geologist at Carleton University in Ottawa, Canada, and Tomsk State University in Russia, who led the work. “These are magnificent huge things.”

Knowing when and where such eruptions occurred can help geologists to pinpoint ore deposits, reconstruct past supercontinents and understand the birth of planetary crust. Studying this type of volcanic activity on other planets can even reveal clues to the geological history of the early Earth.

Ernst presented the findings this month to an industry consortium that funded the work (see ‘Earth’s biggest eruptions’). He expects to make the data public by the end of the year, through a map from the Commission for the Geological Map of the World in Paris.
“This will probably be the defining database for the next decade,” says Mike Coffin, a marine geophysicist at the University of Tasmania in Hobart, Australia.

Surprisingly, the ancient eruptions lurk almost in plain sight. The lava they spewed has long since eroded away, but the underlying plumbing that funnelled molten rock from deep in the Earth up through the volcanoes is still there.

Telltale tips
Ernst and his colleagues scoured the globe for traces of this plumbing. It usually appears as radial spokes of ancient squirts of lava, fanned out around the throat of a long-gone volcano. The geologists mapped these features, known as dyke swarms, and used uranium–lead dating to pinpoint the age of the rock in each dyke. By matching the ages of the dykes, the researchers could connect those that came from a single huge eruption. During their survey, they found evidence of many of these major volcanic events.

Each of those newly identified eruptions goes into Ernst’s database. “We’ve got about 10 or 15 so far that are probably comparable to the Siberian event,” Ernst says, “that we either didn’t know about or had a little taste, but no idea of their true extent.”

They include a 1.32-billion-year-old eruption in Australia that connects to one in northern China. By linking dyke swarms across continents, scientists can better understand how Earth’s crust has shuffled around over time, says Nasrrddine Youbi, a geologist at Cadi Ayyad University in Marrakesh.

Technically, the eruptions are known as ‘large igneous provinces’ (LIPs). They can spew more than one million cubic kilometres of rock in a few million years. By comparison, the 1980 eruption of Mount St Helens in Washington state put out just 10 cubic kilometres.

These large events also emit gases that can change atmospheric temperature and ocean chemistry in a geological blink of an eye. A modelling study published last month suggests that global temperatures could have soared by as much as 7 °C at the height of the Siberian eruptions (F. Stordal et al. Palaeogeogr. Palaeoclimatol. Palaeoecol. 471, 96–107; 2017). Sulfur particles from the eruptions would have soon led to global cooling and acid rain; more than 96% of marine species went extinct.

But the picture of how LIPs affected the global environment gets murkier the further back in time you get, says Morgan Jones, a volcanologist at the University of Oslo. Uncertainties in dating grow, and it becomes hard to correlate individual eruptions with specific environmental impacts. “It’s at the limit of our understanding,” he says.

On average, LIPs occur every 20 million years or so. The most recent one was the Columbia River eruption 17 million years ago, in what is now the northwestern United States.

Discovering more LIPs on Earth helps to put the geological history of neighbouring planets in perspective, says Tracy Gregg, a volcanologist at the University at Buffalo in New York. She and Ernst will lead a meeting on LIPs across the Solar System at a planetary-science meeting in Texas next week.

Venus, Mars, Mercury and the Moon all show signs of enormous eruptions, Gregg notes. On the Moon, LIP-style volcanism started as early as 3.8 billion years ago; on Mars, possibly 3.5 billion years ago. But without plate tectonics to keep the surface active, those eruptions eventually ceased.

“Other planetary bodies retain information about the earliest parts of planetary evolution, information that we’ve lost on Earth,” Gregg says. “They can give us a window into the early history of our own planet.”

Guidelines for writing CV / When to use a Resume in Academic career
« on: March 21, 2017, 05:29:36 PM »
In the United States, most employers use resumes for non-academic positions, which are one or two page summaries of your experience, education, and skills.  Employers rarely spend more than a few minutes reviewing a resume and successful resumes are concise with enough white space on the page to make it easy to scan.

For more information on developing your resume, please visit Optimal Resume and Cornell Career Services Career Guide. Students often find it helpful to review resumes from graduate students who got their first job outside of academe.  To see example resumes, visit the PhD Career Finder in Versatile PhD.

1. If a headphone spec includes very high frequencies above 23,000Hz, that's a good sign, and the headphone might sound clearer than a headphone with a 18,000Hz spec

2. The best bass is only achievable when the earpieces have an airtight seal

3. Home amps are more powerful than portable devices, and AC-powered amps produce more bass and tend to sound better with higher impedance headphones
With smartphones and portable music players, low-impedance headphones of 32 ohms or less are recommended. At home impedance is less of an issue, but Grell recommends higher-impedance models.

4. Larger drivers do a poor job reproducing high frequencies. Grell says the maximum driver size should be around 42mm (for full-size headphones); with larger drivers the surface of the diaphragm physically changes shape at high frequencies and produces irregular frequency response. Larger drivers can generate cleaner bass, but less accurate high frequencies.
5. "Trust your ears."
