1-. አልበርት አንስታይን

አንስታይን ከ1879-1955 የኖረ ታላቅ የሳይንስ ሊቅ ነበር። በተለይ ሁለት ግኝቶቹ የሳይንስ እይታችንን በእጅጉ የቀየሩ ሲሆን አንስታይን ምድራችን ካፈራቻቸው የሳይንስ ሊቆች ውስጥም ሆነ ወደፊት ከሚወለዱት ውስጥ ተወዳዳሪ አይገኝለትም የሚባል ብርቅዬ ሳይንቲስት ነው።

አንስታይን በልጅነቱ ዳይስሌክሊስ (ሲያነቡ ወደ ግራ የሚያነቡ) የነበረ ሲሆን በትምህርቱ ደካማ በመሆኑ አስተማሪዎቹ ደደብ አድርገው ይገምቱት ነበር።

በ15 ዓመቱ ትምህርቱን አቁሞ ከዓመት በኋላ ዙሪክ የሚገኝ አንድ ፖሊ ቴክኒክ ለመግባት አመልክቶ የመግቢያ ፈተናውን ወድቋል።

ይህ ሰው ግን በፊዚክስ ንድፈ ሃሳብ ዓለምን በመቀየሩ የኖቬል ሽልማት ለመሸለም የበቃ ድንቅ ሳይንቲስት ነው።

2- ቤንጃሚን ፍራንክሊን

ይህ ሰው የሂሳብ ትምህርት አይሆነውም ነበር። እናም አባቱ ከትምህርት ቤት አስወጥቶ ሻማና ጧፍ ሲያሰራው አደገ። ነገር ግን ይህ ሰው አሜሪካ ካፈራቻቸው ታላላቅ ሰዎች አንዱ በመሆን ታዋቂ ፖለቲከኛ፣ ሳይንቲስት፣ ጸሐፊ እና የፔንሲልቫኒያ ፕሬዚዳንትና የአሜሪካ መስራች አባት ለመባል የበቃ ሰው ነው።

3- ቻርለስ ዳርዊን

ወጣቱ ዳርዊን በትምህርቱ በመድከሙ አባቱ "አንተ ከአደን እና ውሻ በስተቀር የምትወደው ነገር የለም፤ ስለዚህ ለራስህም ሆነ ለቤተሰብ ውርደት እንዳትሆን" ብሎ ከትምህርት ቤት አስወጣው።

የህክምና ትምህርት ሞከረ አስጠላው። የሃይማኖት ትምህርትም ሞክሮ ነበር አልሆነለትም። ብዙውን ግዜውን ግን ከስፖርተኞች ጋር ነበር የሚያጠፋው።
ይህ ሰው ግን በመጨረሻ አጠቃላይ የስነ-ህይወት ሳይንስን ለመቀየር ችሏል።

4- ሴናተር ኤድዋርድ ኤም ኬኔዲ

ይህ የማሳቹሴትስ ሴናተር በአንድ ወቅት ለአሜሪካ ፕሬዚዳንትነት ሁሉ ተወዳድሯል። ግን ፈተናውን ጓደኛው ሲፈተንለት ተይዞ ከሚማርበት ሃርቫርድ ዩኒቨርስቲ ተባርሮ ነበር።

5- ሰር ዊንስተር ቸርችል

ይህ ሰው ታላቅ እንግሊዛዊ ፖለቲከኛ፣ ገጣሚ፣ ደራሲና ሰዓሊ ሲሆን እንግሊዝን በአንደኛ እና ሁለተኛ የዓለም ጦርነት በተለያየ የመንግስት ስልጣን ደረጃ የመራ ታላቅ የፖለቲካ ሰው ነው። (በአገራችን መዲና አዲስአበባ ጎዳና በስሙ ተሰይሞለታል)

ቸርችል ይህቺ ምድር ካፈራቻቸው ድንቅ የፖለቲካ ሰዎች አንዱ ቢሆንም በትምህቱ ደካማ ስለነበር ሮያል የውትድርና ኮሌጅ ለመግባት ከአንዴም ሁለት ግዜ ተፈትኖ በመውደቁ መግባት አልቻለም ነበር።

6- ቶማስ ኤድሰን

ይህ ታላቅ ፈላስፋ ትምህርት ቤት የሄደው ለሶስት ወራት ብቻ ነበር። ምክንያቱም በስምንት ዓመቱ አስተማሪው "ደደብ" ብሎ ስለሰደበው እናቱ ከትምህርት ቤት አውጥታ ቤት ውስጥ አስተማረችው። በዘጠኝ ዓመቱ ይሞክራቸው የነበሩት ነገሮች ከእናቱ አቅም በላይ ሆኖ ተገኝቷል።

ቶማስ ኤድሰን በህይወት ዘመኑ አንድ ሺህ አዳዲስ ግኝቶችን የፈለሰፈ ሲሆን ከእነዚህ ውስጥ የኤሌክትሪክ ብርሃን እና ሸክላ ማዘፈኛ ሲኖሩበት ያሻሻላቸው ነገሮች ደግሞ ፊልም ማሳያ፣ ቴሌፎን ይገኙበታል።

7- አይዛክ ኒውተን

ይህ ሰው ደካማ ውጤቶች ስለነበሩት ከትሪንቲ ኮሌጅ ሆነ ከካምብሪጅ ዩኒቨርስቲ ሲመረቅ የክብር ወይም የማዕረግ ተመራቂ አልነበረም።

ነገር ግን በታሪክ ከታወቁት ታላላቅ የሳይንስ ፈጣሪዎች አንዱ በመሆን የዘመኑ ሳይንስ በእርሱ ስራዎች ላይ ለመመርኮዝ በቅተዋል።

Inversion

Subject + verb + object

ይህ 👆መደበኛው የsentence structure ሲሆን የ inversion ደሞ ይህን ይመስላል👇

Verb + subject + object

inversion ማለት ደራሲያን ድርሰታቸው ውበት እንድኖረው ለማድረግ ከሚጠቀሙበት የአፃፃፍ ጥበብ ውስጥ አንዱ ነው።

አንድን sentence inversion ለማድረግ የ sentenceኡን verb እና subject ቦታ ማቀያየር ነው፤ ነገር ግን ሁሉም ዐ.ነገር Inversion አይደረግም።
ወደ Inversion የሚቀየሩት sentenceኦች ውስን ናቸው እነሱም👇

1️⃣ Conditional Sentences

There are 3 types of  Conditional sentence. ታዲያ 3 ቱም type Inversion ይደረጋሉ። እስኪ እንያቸው

     💠 Probable condition

Probable condition ን Inversion ለማድረግ ፡
👉 "if" ን አጥፍተን🚫 በ "if" ቦታ "should" ን ማስገባት።

Example: If you study hard , you will pass the exam.

👆ይኸን probable condition ወደ Inversion ለመቀየር ፡ በ "if" ቦታ "should" ን ማስገባት ነው። ስለዚህ፡

if you study hard , you will pass the exam የሚለውን condition ስንቀይረው👇

Should you study hard , you will pass the exam. ይሆናል

🔻"you" subject ነው "study" ደሞ verb. If you study hard ሲል Subject +Verb ነው የተጠቀመው ይህ ደሞ norma የsentence structure ነው።
🔻"should" የሚለው Verb ነው። "you" የሚለው ደግሞ subject
ስለዚህ Should you 🟰 verb + subject ሆነ። በሌላ አባባል Inversion ሆነ ማለት ነው።

⭐️ፈተና ላይ ልትጠየቁ ምትችሉት እንደዚህ አይነት ነው👇

........ I arrive early, I will finish all tasks.

A) should     C) may
B) would       D) could

መልሱ "A" ይሆናል ማለት ነው።

     💠 Improbable condition

improbable condition ን ወደ Inversion ለመቀየር ፡

👉 "if" ን አጥፍተን የ subject ቱንና የ verb ቡን ቦታ ማቀያየር ።
Example: If he were a bird , he would fly.

👆 ይኸንን improbable condition ወደ Inversion ለመቀየር፡
"if" ን እናጠፋለን። ከዛ የ subject ቱን ና verb ቡን ቦታ መቀያየር። ማለትም የ "he" ና የ "were" ን ቦታ መቀያየር። ስለዚህ

If he were a bird , he would fly.
የሚለውን condition ስንቀይረው👇

Were he a bird , he would fly. ይሆናል
🔻he were a bird 🟰 subject + verb + object የሚለውን structure ነው የተጠቀመው። ቦታ ስናቀያይር ደሞ:
🔻were he a bird ሲል ደሞ the reverse Verb + subject + object የሚለውን የ inversionንን structure ነው የተጠቀመው cuz "were" verb ነው "he" ደሞ Subject 

Question
......... they football, they wouldn't come early.(Inversion)
A) play     C) played
B) was playing      D) should

መልሱ "C" ይሆናል

✨እዚህጋ እንዳትዘናጉ Shouldን ምንጠቀመው ለ probable condition እንጂ ለImprobable condition አይደለም ለዛ መልሱ D, should አይሆንም‼️

👉 እንዴት improbable እንደሆነ አወቅን? 🤔
Main clauseዙ ላይ wouldn't ነው ሚለው የ will negative past form ማለት ነው ነገር ግን will or won't ቢሆን ኖሮ sentenceኡ probable ይሆን ነበር።

✨ለimprobable condition ጊዜ verbu በ past participle (V3) form መቀመጥ ስላለበት a, play እና b, was playing አይሆንም ስለዚህ መልሳችን C, played ይሆናል ማለት ነው።

     💠 Impossible condition

impossible condition ን ወደ Inversion ለመቀየር፡

"if" ን ካጠፋን በሗላ የ subject ቱን ና የ verb ቡን ቦታ ማቀያየር።
👌እዚህጋ ማስተዋል ያለብን ነገር ቦታ ስናቀያይር ፡ ቦታው የሚቀየረው verb "had" ብቻ ነው።

Example: If I had known the answer , I would have told you.

👆 ይኸንን impossible condition ወደ Inversion ለመቀየር ፡ የ subject ቱን ና የ verb ቡን ቦታ ማቀያየር። ማለት የ "I" ን ና የ "had" ን ቦታ ማቀያየር። ስለዚህ

🤐 Had I known the answer, I would have told you.( Inversion).
ይሆናል

🔻Had(verb) + I(subject)= inversion

Example: if corona hadn't been occurred , we wouldn't have stayed at home😢.(impossible condition)

😷Hadn't corona been occurred , we wouldn't have stayed home.( Inversion)

🔻Hadn't(verb) + corona( subject)= inversion

‼️Attention: Entrance exam ላይ Inversion ተብሎ ፈተና አይወጣም instead :

if clause ላይ Inversion አድርገው ፡ main clause ዙ ምንድን ነው የሚሆነው?😳 የሚል ጥያቄ ነው ሚሆነው።

Example: Had Entrance candidate studied well , they ........ the exam.

A) wouldn't have failed
B) would have failed
C) wouldn't failed
D) won't fail

Answer:
እዚህጋ ፈጥነን🏃‍♂️🏃‍♀️ማየት ያለብን Inversion የተደረገው if clause የትኛው conditional sentence ላይ እንደሆነ ነው። ይኸን ካወቃችሁ ሌላው ቀላል ነው😌

ቅድም እንደነገርኳችሁ impossible condition ወደ Inversion ሲቀየር "had" ቀድሞ ይመጣል ከዛ ቀጥሎ "subject" ከዛ ቀጥሎ "verb 3" ይመጣል። ስለዚህ በዚህ ጥያቄ መሰረት

Had + candidates + V3

ስለዚህ ዐረፍተ ነገሩ impossible condition ነው። impossible condition ላይ ደግሞ main clause ሊሆን የሚችሉት:
Would(n't)+ have + V3
Could(n't) + have + V3
Might(n't)+ have + V3
ናቸው።

በዚህ ጥያቄ መሰረት ምርጫ ላይ ያለው wouldn't and would ነው።

ስለዚህ መልሱ"A" ይሆናል

Had Entrance candidate studied well, they wouldn't have failed the exam.(Inversion) በሌላ አባባል:

1. Newton's First Law: The Law of Inertia

•  Brief Explanation: Objects like to keep doing what they're already doing. If they're still, they stay still; if they're moving, they keep moving at the same speed and direction, unless a force messes with them.
•  Key Idea: Inertia is the tendency to resist changes in motion.

2. Newton's Second Law: The Law of Acceleration

•  Brief Explanation: When a force acts on an object, it causes the object to accelerate (speed up, slow down, or change direction). The bigger the force, the bigger the acceleration. The bigger the object's mass, the smaller the acceleration for the same force.
•  Key Idea: Force causes acceleration (F = ma).

3. Newton's Third Law: The Law of Action-Reaction

•  Brief Explanation: Every time one object pushes or pulls on another, the second object pushes or pulls back with the exact same strength in the opposite direction. Forces always come in pairs.
•  Key Idea: Forces come in action-reaction pairs.

Analogy for All Three Laws:

Imagine a bowling ball and a soccer ball:

1. First Law: If both balls are still, they'll stay still (inertia). If one was rolling, it'd keep rolling in the same direction at the same speed if nothing interfered.

2. Second Law: If you kick both with the same force, the lighter soccer ball will accelerate much more than the heavier bowling ball. The more forcefully you kick, the more they both accelerate.

3. Third Law: When your foot kicks the ball (action), the ball also pushes back on your foot equally hard (reaction). That's why you feel a force on your foot.

In a Nutshell:

•  Law 1: Things resist change.
•  Law 2: Force causes change (acceleration).
•  Law 3: Forces are mutual (action-reaction).

Specific Elements and Their Meanings:

•  "Cell" Label: The doorframe is labeled "Cell." This indicates that the entire image represents the inner workings of a cell. The door itself represents the membrane of a cell.
•  "Glucose": The person outside the door is labeled "glucose." This is the starting molecule for cellular respiration.
•  Inside the Door (Processes of Cellular Respiration):
  •  "Glycolysis": The girl peering through the door opening is labeled "glycolysis." This represents the first step of cellular respiration which breaks down the glucose molecule to start the process.
  •  "Krebs Cycle": The boy wielding a knife looking through the door opening is labeled "Krebs Cycle". This represents the second step of cellular respiration where the products of glycolysis are further processed.
  •  "Electron Transport Chain": The woman in an orange dress holding a knife is labeled "electron transport chain". This represents the third part of cellular respiration.
